For the Whole Family
The HBF-400 supports up to four personal profiles, so each member of your family can track their own measurements independently. Plus, an easy-to-read and large digital display makes it a snap to get the information you need.

Detailed Measurement
The weight display measures weight up to 330 pounds in .2-pound increments, while body fat percentage can be measured from 5 to 60 percent in .1 percent increments.

One of the keys to weight loss and management is tracking your body mass index, or BMI. The HBF-400 rates your BMI from 7.0 to 90.0 in .1 increments. BMI is classified at three levels: underweight, normal, overweight, and obese.

Made for Just about Everyone
The HBF-400 is set up to provide measurements for folks of nearly all heights (3'4" to 6' 6-3/4") and nearly all ages (10 to 79 years). Measurements are customized for males and females, as well.

Power and Dimensions
The HBF-400 runs on four AA batteries, and you can expect about a year of battery life when the device is used four times a day. The unit measures 12.2 x 11.8 x 2.1 inches (L x W x H). The unit weighs 4.7 pounds.

What is the Bioelectrical Impedance Method?
Bioelectrical Impedance (BI) is considered one of the most accurate and accessible methods of screening body fat. Muscles, blood vessels and bones are body tissues having a high water content that conduct electricity easily. Body fat is tissue that has little electric conductivity. The monitor sends an extremely weak electrical current through your body to determine the amount of fat tissue. The weak electrical current is not felt while operating the Body Fat Analyzer. The monitor is calculated by a formula that includes five factors; electric resistance, height, weight, age and gender.
What is visceral fat?
Visceral fat is located around the organs. Too much visceral fat is thought to be closely linked to increased level of fat in the bloodstream, which can lead to common conditions such as high cholesterol, cardiovascular disease and diabetes. Sedentary life style causes excess visceral fat, and exercise can reduce it quicker than subcutaneous fat (fat located under skin).
What is resting metabolism?
Resting metabolism is the energy to maintain vital functions and it counts 60 to 70% of total energy consumption. Knowing your resting metabolism can help your dietplan. If you can increase daily activity while keeping food intake at resting metabolism level, you can lose weight.
What is skeletal muscle?
Skeletal muscle is muscle attached to the bones that is used to move the body. If you do weight loss without exercise, you may lose skeletal muscle. Skeletal muscle is important to maintain your resting metabolism as well as your functionality. Monitoring skeletal muscle during weight loss is key to avoid weight rebound in the future.
