MOMAX Lite Tracker EW2S IoT Body Scale
Brand: MOMAX
Model: EW2S
Introduction
How does Lite Tracker (EW2S) work?
This model applies BIA (Bioelectrical Impedance Analysis) technology, which makes measurement based on the study of conductive composition of muscle and water contents within the body. A small amount of weak current flow through the human body so as to detect the bio-impedance and estimate BMI, body fat, body water, muscle mass, bone mass, etc. The BIA technology is safe, non-invasive, toxic-free and harmless. It is easy to operate and provide comprehensive information.

Appendix - Body Composition Data
1. Health Tips - About Body Fat
Human body is made up of a percentage of fat. Body fat is vital for a healthy, functioning body, protects vital organs, helps regulate body temperature, stores vitamins and helps the body sustain itself when food is scarce. However, too much body fat or indeed too little body fat will damage your health. It is difficult to gauge how much body fat we have in our bodies simply by looking at ourselves in the mirror.
This is why it is important to measure and monitor your body fat percentage. Body fat percentage gives you a better measure of fitness than weight alone—the composition of your weight loss could mean you are losing muscle mass rather than fat—you could still have a high percentage of fat even when a scale indicates 'normal weight'.
The body fat percentage (%) : 5% - 60% / 0.1%
Table of body fat rating
Rating | Age | ||||
---|---|---|---|---|---|
20-29 | 30-39 | 40-49 | 50-59 | 60+ | |
Low | <13.0 | <14.0 | <16.0 | <17.0 | <18.0 |
Normal | 13.0-20.0 | 14.0-21.0 | 16.0-23.0 | 17.0-24.0 | 18.0-25.0 |

2. Health Tips - About Body Water
Body water is the single most important component of body weight. It represents over half of your total weight and almost two-third of your lean body mass (predominantly muscle). Water performs a number of important roles in the body:
All the cells in the body, whether in the skin, glands, muscles, brain or anywhere else, can only function properly if they have enough water. Water also plays a vital part in regulating the body's temperature balance, particularly through perspiration.
The combination of your weight and fat measurement could appear to be 'normal' but your body hydration level could be insufficient for healthy living.
The body water percentage (%) : 43% - 73% / 0.1%
Table of body water level (Unit: %)
Gender | Body Fat Percentage Range | Optimal TBW % Range | ||
---|---|---|---|---|
Men | 4% to 14% | 70% to 63% | ||
15% to 21% | 63% to 57% | |||
22% to 24% | 57% to 55% | |||
25% and over | 55% to 37% | |||
Women | 4% to 20% | 70% to 58% | ||
21% to 29% | 58% to 52% | |||
30% to 32% | 52% to 49% | |||
33% and over | 49% to 37% |
3. Health Tips - About Muscle Mass
According to the American College of Sports Medicine (ACSM), lean muscle mass may decrease by nearly 50 percent between the age of 20 and 90. If you do nothing with it you're losing muscle and increasing fat. It is also important to know your muscle mass % during weight reduction. At rest, the body burns approximately 110 additional calories for each kilo of muscle gained. Benefits of gaining muscle mass include:
- Reversing the decline in strength, bone density and muscle mass with aging
- Maintenance of flexible joints
- Guide weight reduction when combined with a healthy diet.
Muscle Mass Percentage
Gender | Percentage |
---|---|
Men | Approximately 40% of total body weight |
Women | Approximately 30% of total body weight |
4. Health Tips - About Bone Mass
Regular exercise and a balanced diet can help maintain healthy bones. Like muscle, bone is a living tissue that can respond to exercise by becoming stronger. For most people, bone mass peaks in their thirties. Then people begin to lose bone mass. Regular exercise can help prevent that loss.
Calcium and vitamin D, good sources of which are dairy products, green leafy vegetables and fish, contribute to healthy bones.
The bone mass readings given by this product are an estimation of the amount of bone in your body. Those with osteoporosis or low bone densities may not get accurate estimations. If you have any concern regarding your bones please consult your doctor timely.
Bone Mass Percentage
- The average bone mass percentage for both men and women is between 4 to 5%.
Table of bone mass between gender and age
Sex | Age | Bone Mass Index | |||
---|---|---|---|---|---|
Low (-) | Normal (0) | High (+) | Very High (++) | ||
Men | 20-39 | <8.0 | 8.0 - 19.9 | 20.0 - 24.9 | > 25.0 |
40-59 | <11.0 | 11.0 - 21.9 | 22.0 - 27.9 | > 28.0 | |
60-79 | <13.0 | 13.0 - 24.9 | 25.0 - 29.9 | > 30.0 | |
Female | 20-39 | <21.0 | 21.0 - 32.9 | 33.0 - 38.9 | > 39.0 |
40-59 | <23.0 | 23.0 - 33.9 | 34.0 - 39.9 | > 40.0 | |

5. Health Tips - About BMI
Maintaining proper weight is essential to healthy living. Obesity has been linked to a higher risk of heart disease, diabetes and some forms of cancer. The Body Mass Index (BMI) is the most widely accepted measurement of weight according to health professionals. The Analyzer will calculate your BMI on your height and weight.
6. Health Tips - About Calorie
The device uses your age, height, gender and an activity level setting to calculate the estimated number of calories you can consume a day to maintain your present weight. This estimation may gradually help you with a weight loss, gain or maintenance plan.
