InBody 270S vs TANITA MC-780MA vs ACCUNIQ BC380 for Gyms Choosing Body Composition Analyzer
Key takeaways: The InBody 270S, TANITA MC-780MA and ACCUNIQ BC380 are all professional body composition analyzers with eight electrodes, multiple frequencies and five-segment measurement, and all three can connect to Trainge Smart Measurement. The right choice depends on your venue, not on which brand is "better". If you need portability or have limited space, look at the foldable InBody 270S with its 13.4 kg main unit. If your members cover a wide weight range and you want an athlete mode plus intracellular and extracellular water data, look at the TANITA MC-780MA with its 270 kg capacity. If your budget is tight in the early stage of operation, consider the ACCUNIQ BC380.
Which of the three analyzers should your venue choose?
Choose a body composition analyzer by looking at your venue scenario first and the spec sheet second. The InBody 270S, TANITA MC-780MA and ACCUNIQ BC380 share the same measurement principle, multi-frequency bioelectrical impedance analysis. They differ mainly in body design, data items, peripheral options and data output. The table below is organized by common venue scenarios, and the three models are not ranked.
| Venue scenario | Consider first | Why |
|---|---|---|
| Personal training studio, limited space, or measurements taken off-site at companies and events | InBody 270S | Foldable, portable design with a 13.4 kg main unit and built-in Wi-Fi and Bluetooth |
| Wide member weight range, athletes or strength-training members, interest in intracellular and extracellular water and phase angle | TANITA MC-780MA | 270 kg maximum capacity, standard and athlete body-type modes, and built-in casters |
| You want to complete equipment purchase and member-system integration in one go | InBody 270S or TANITA MC-780MA | Most sports venues working with Trainge use measurement devices from these two major brands, which have delivered stable measurements over long-term use, and both can be set up to integrate with the Trainge system |
| Limited budget in the early stage of operation, but you want the core measurement items of a professional model | ACCUNIQ BC380 | Like the other two, it uses eight electrodes, three frequencies and five-segment measurement. Confirm the actual price difference with distributor quotes, and also assess how familiar your members are with the brand |
| You already own one of the three and want to connect it to a member system | Keep your current model | All three can connect to Trainge Smart Measurement, so there is no need to replace a machine for the sake of the system |

What is a professional body composition analyzer, and why do venues need one?
A professional body composition analyzer is a measurement device that uses bioelectrical impedance analysis (BIA) to estimate body fat, muscle mass and body water. The device passes a weak electrical current through the body and estimates body composition from the different impedance of different tissues. Professional models differ from home body fat scales in three main ways: they use eight electrodes, they measure at multiple frequencies, and they measure five segments separately, namely both arms, both legs and the trunk.
For a venue, the value of a body composition analyzer is that it turns training results into visible numbers. A new member gets a baseline at sign-up and is then re-measured every four to eight weeks. Coaches can adjust programs based on changes in muscle mass and body fat, and members who can see their progress are more likely to renew.
Reminder: In Taiwan, all three models are sold as medical devices. Measurement results are reference data for body management and cannot replace a physician's diagnosis. Different brands and models use different algorithms, so their numbers should not be compared with each other. When tracking change over time, always use the same machine.
How do the three models differ in specifications?
All three use eight electrodes, three frequencies and five-segment measurement. The main differences are the frequency set, main unit weight, maximum capacity and data output. Every specification below is taken from each brand's published manufacturer materials, checked in September 2026.

What kind of venue is the InBody 270S suited to?
The InBody 270S suits venues with limited space, venues that need to move the machine, and venues that want members to receive results directly on their phones. It is the portable model in InBody's professional line. The body folds, and at 13.4 kg the main unit is the lightest of the three.
- Body design: Foldable and portable. It fits one-on-one personal training studios and also works for outreach measurements at companies or events.
- Measurement method: Uses three frequencies (20, 50 and 100 kHz) to take 15 impedance values across five segments, namely both arms, both legs and the trunk. A measurement takes about 30 seconds.
- Result sheet: Includes weight, skeletal muscle mass, body fat mass, percent body fat, segmental muscle and fat analysis, visceral fat level, basal metabolic rate and whole body phase angle, and keeps a history of the last eight measurements.
- Connectivity: Built-in Wi-Fi and Bluetooth. The Taiwan official site states that results can be retrieved by QR code.
The InBody 270S is the successor to the older InBody 270. According to manufacturer materials, the 270 uses two frequencies (20 and 100 kHz) to take 10 impedance values, while the 270S uses three frequencies to take 15 impedance values and adds whole body phase angle. If the quotation you receive says 270, confirm with the distributor which model will actually ship.

What kind of venue is the TANITA MC-780MA suited to?
The TANITA MC-780MA (often shortened to Tanita MC-780) suits venues whose members cover a wide weight range, venues with athletes or strength-training members, and venues that want more water and cell-related data. Its maximum capacity is 270 kg, the highest of the three, and the unit is made in Japan.
- Measurement method: Multi-frequency with eight electrodes, using 5, 50 and 250 kHz. A measurement takes less than 30 seconds.
- Data items: The Taiwan official site lists 16 whole body items, 10 segmental items and 16 special items, including intracellular water, extracellular water, phase angle, leg muscle score, skeletal muscle index (SMI) and metabolic age. The full data set requires GMON software, which is a paid option.
- Body-type modes: Offers "standard" and "athlete" modes. Athlete mode applies to ages 18 to 99 and suits members with a high training volume.
- Body design: The main unit weighs 15.5 kg, the column is 1,165 mm high, and casters let you move it around the venue. It comes in dark grey, white and black.
- Data output: Supports SD card storage, RS-232C and USB connections, and direct printing to a PictBridge printer.
Pay attention to software and connectivity when buying the MC-780MA. It has no built-in Wi-Fi, so getting data into a member system means transferring it through a port to a computer or an integration service. Confirm your front desk hardware setup before ordering.

What kind of venue is the ACCUNIQ BC380 suited to?
The ACCUNIQ BC380 is a practical choice when budget is limited, suited to venues in the early stage of operation that want the core measurement items of a professional model first. Like the other two, it uses eight electrodes, three frequencies and five-segment measurement. Confirm the actual price difference with distributor quotes. ACCUNIQ is a brand of South Korea's SELVAS Healthcare, and its general distributor in Taiwan is 驊晟有限公司.
- Measurement method: Eight touch electrodes using 5, 50 and 250 kHz, measuring the whole body and five segments, with a maximum capacity of 250 kg.
- Notable data: The result sheet includes the extracellular water ratio (extracellular water as a share of total body water, used to assess water balance), abdominal obesity analysis, and balance assessment between upper and lower body and between left and right sides.
- Peripheral options: Can optionally connect to ACCUNIQ's automatic blood pressure monitor and ultrasonic stadiometer, combining blood pressure, height and body composition on one result sheet.
- Body design: The hand electrodes connect to the main unit by cable, and the manufacturer states that anyone from children to adults 220 cm tall can be measured in a natural posture. The main unit weighs about 18 kg and comes in white or black.
- Data management: The machine itself can register members and accumulate records, and after a measurement the ACCUNIQ Connect app can scan a QR code to retrieve the data. Bluetooth requires an optional module.
The BC380 has the heaviest main unit of the three, so it is better placed permanently in a measurement area than moved often. Before buying, also assess how familiar your members are with the brand, because whether members recognize the brand on the result sheet affects the appeal of your measurement service.
How should you estimate price and ongoing costs?
Budget for a professional body composition analyzer as "machine price plus five years of running costs", not the machine quotation alone. Taking the InBody 270S as an example, the Taiwan general distributor's listed price on public channels is about NT$350,000 (checked September 2026). The TANITA MC-780MA and ACCUNIQ BC380 have no public listed price in Taiwan, so you need to request quotes from distributors.
Beyond the machine itself, these five costs are often overlooked:
- Management software: TANITA's GMON software, for example, is a paid option. Ask before buying whether the full data set requires separate software.
- Consumables: Result sheets, thermal paper and electrode cleaning supplies. The more measurements you run, the more you spend.
- Optional peripherals: Stadiometers, blood pressure monitors, printers and Bluetooth modules are all priced separately.
- Warranty and repair: Warranty length differs by brand. The TANITA Taiwan site, for example, lists a 1-year warranty for the MC-780MA. Ask in advance about calibration and repair costs after the warranty ends.
- System integration: Getting data into a member system automatically may involve a monthly fee or a one-time setup fee.
Payment method also affects cash flow. Trainge offers installment and leasing plans. For a newly opened venue that needs to keep cash for rent and fit-out, turning a one-time expense into monthly payments makes planning easier. Trainge holds a medical device dealer license in Taiwan (中市醫材販字第 MD6203032646 號).
Which 6 things should you confirm before buying?
Confirm the following six things before buying a body composition analyzer, so you do not discover after delivery that it does not fit your venue.
- Confirm the location: The measurement area needs a level, hard floor and a power outlet, with room for members to take off their shoes, stand and open their arms.
- Estimate monthly measurement volume: Volume determines your consumables budget and whether to replace printed sheets with results on the phone.
- Decide where the data goes: Printed only, stored on the machine, or sent automatically to a member system. This determines the connectivity you need.
- Request an itemized quote: Ask the distributor to price the main unit, software, peripherals, installation and training separately.
- Confirm license and warranty: Confirm the medical device license number, warranty length and repair contact with the distributor.
- Arrange a hands-on trial: Ask the distributor for a demo unit and have your coaches run the full process once before deciding.
How does measurement data get into your venue back office?
Trainge Smart Measurement syncs measurement data from InBody, TANITA and ACCUNIQ devices to your venue back office automatically, with no manual entry and no paper to file. Trainge is a sports venue management platform from Taiwan that brings together booking, payments, access control and measurement data, and currently serves more than 200 venues.
Once connected, a venue can do three things:
- When a member finishes a measurement, the data is filed under that member's account automatically.
- Members view their own measurement history and trends on their phones.
- Coaches pull up a client's records before a session and adjust the program based on the changes.
Smart Measurement can be used on its own, so venues that already use another booking system do not need to switch. The monthly fee is NT$1,000. To learn which venue types the system supports and how onboarding works, see the Trainge FAQ for venues and coaches (in Traditional Chinese), or visit the Trainge store to see the venue equipment currently listed.
Frequently asked questions
The InBody 270S is the successor to the InBody 270. According to manufacturer materials, the InBody 270 uses two frequencies (20 and 100 kHz) to take 10 impedance values, while the InBody 270S uses three frequencies (20, 50 and 100 kHz) to take 15 impedance values and adds whole body phase angle. Both are foldable, portable models.
All three are professional models licensed as medical devices and share the same principle, multi-frequency bioelectrical impedance analysis. Each brand uses its own algorithm, so their numbers should not be compared with each other. For a venue, what matters more than which one is more accurate is using the same machine every time, at a similar time of day and in a similar physical state, and tracking the trend.
Professional eight-electrode, multi-frequency models are mostly priced in the hundreds of thousands of New Taiwan dollars. Taking the InBody 270S as an example, the Taiwan general distributor's listed price on public channels is about NT$350,000. The TANITA MC-780MA and ACCUNIQ BC380 have no public listed price, so you need to request quotes from distributors and budget separately for software, consumables and peripherals.
Yes. Trainge Smart Measurement can be used on its own without replacing your current booking system, for a monthly fee of NT$1,000. Once connected, measurement data syncs to the back office automatically and members can view their measurement history on their phones.
Most venues measure new members once at sign-up to set a baseline, then re-measure every four to eight weeks. Body composition takes time to change, and measuring too often makes results sensitive to that day's hydration, which can make members anxious. Measure at a similar time of day, fasted or at least two hours after a meal, and before exercise.
A body composition analyzer passes a weak electrical current through the body. People with implanted electronic medical devices such as pacemakers should not use one, and anyone who is pregnant should consult a physician first. Follow the manufacturer's user manual for the full precautions for each model. Venues should post a reminder in the measurement area and have staff ask members in advance.
