1. Product Overview
The InBody H20N is a smart full body composition analyzer scale designed for home use, providing comprehensive insights into your body's health beyond just weight. It utilizes advanced Bioelectrical Impedance Analysis (BIA) technology to measure various body composition parameters.
- Winner of the Men's Health Tech Award 2022 for best smart fitness scale.
- Features handlebar electrodes for full body assessment, ensuring more accurate and consistent body composition results compared to scales that only measure half the body.
- Results automatically sync to your smart device via the InBody app (available for Google Android and Apple iOS) for progress tracking, goal setting, and comparison.

3. Operating Instructions
Follow these steps for accurate body composition measurements.
3.1 Taking a Measurement
- Preparation: Ensure the scale is placed on a hard, flat, and level surface. Avoid carpets or uneven flooring. For best results, measure at the same time of day, ideally in the morning before eating or exercising. Ensure your feet are clean and dry, and avoid applying lotion before measurement.
- Step On: Step onto the scale barefoot, placing your feet on the designated electrode areas. Stand still with your feet aligned.
- Hold Handlebar: Grasp the handlebar firmly with both hands, ensuring your thumbs are on the thumb electrodes and your palms are on the palm electrodes. Keep your arms straight but relaxed, not touching your body.
- Measurement Process: The scale will begin the measurement. Remain still and quiet until the measurement is complete. The display on the scale will show your weight, and the full body composition analysis will be sent to your InBody app.
- Review Results: Open the InBody app on your paired device to view your detailed body composition report, including weight, skeletal muscle mass, body fat mass, and more.

3.2 Best Practices for Accurate Results

Figure 3.3: An infographic illustrating the recommended "DOs" and "DONTs" for taking an InBody measurement to ensure accurate and reliable results. This includes measuring at the same time of day, using a hard level surface, and avoiding measurements right after exercise or with wet skin.
- DOs:
- Measure at the same time of day.
- Use on a hard, level surface.
- Stand still and keep your feet aligned.
- DONTs:
- Measure right after exercise.
- Use immediately after eating or drinking.
- Measure with wet or lotion-applied skin.
3.3 Understanding Your Results
The InBody app provides a detailed breakdown of your body composition. Key metrics include:
- Weight: Your total body weight.
- Skeletal Muscle Mass (SMM): The amount of muscle attached to your bones. Higher SMM is generally desirable.
- Body Fat Mass (BFM): The amount of fat in your body.
- Body Mass Index (BMI): A measure of body fat based on height and weight.
- Percent Body Fat (PBF): The percentage of your total weight that is fat.
The app allows you to track changes over time, set personal goals, and gain a deeper understanding of your health and fitness journey.

4. Maintenance
Proper maintenance ensures the longevity and accuracy of your InBody H20N.
4.1 Cleaning
- Wipe the surface of the scale and handlebar with a soft, damp cloth.
- Do not use abrasive cleaners, harsh chemicals, or immerse the device in water.
