It is also an excellent tool to measure your body fat percentage and body mass on a continuous schedule. It is an accurate, validated device for home, clinical and fitness use.
The Omron BF306 Body Fat Monitor features a handy 9-user memory so can be used by a group of different people. The monitor is easy to use and all you have to do is stand with your feet shoulder length apart, input data, hold the monitor straight in front of you and press start. Within a minute the measurement is ready. This validated medical device has been developed and endorsed by specialists.
The Omron BF306 Body Fat Monitor has a sturdy design and its software can measure bodies of up to 199kg. There is normal or athlete mode for more accurate measurements, and body fat percentage and body mass index are shown simultaneously in an easy-to-see large digital display and a bar display that can be read at a glance.
Body fat percentage refers to the amount of body fat mass in regards to the total body weight described in a percentage. The Omron BF306 Body Fat Monitor estimates the body fat percentage by the Bioelectrical Impedance (BI) method.
What is the Bioelectrical Impedance Method?
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 Body Fat Analyzer sends an extremely weak electrical current of 50 kHz and 500 µA through your body to determine the amount of fat tissue. This weak electrical current is not felt while operating the Body Fat Analyzer.
The Bioelectrical Impedance Method safely combines the electric resistance with the distance of the electricity conducted. Correct posture and consistent measuring conditions need to be maintained for the best results.
How to estimate the body fat percentage
Hydrodensitometry, or underwater weighing, has been the established method for accurate evaluation of body composition. Omron has used research information from several hundred people using the underwater weighing method to develop the formula by which the Body Fat Analyzer works. The body fat mass and body fat percentage is calculated by a formula that includes five factors: electric resistance, height, weight, age and gender.
What is the submerged body weight weighing method?
The underwater weighing method submerges a person in a pool from head to toe to be weighed. Omron has collected information on people from 10 to 80 years of age using this method.
(There are certain conditions, such as with dialysis patients, when significant differences may occur between the estimated and actual body fat values. These differences may be related to consistently changing ratios of body fluid and/or bone density).

How to Measure: How to Interpret the Measured Results
Body fat percentage Displays the body fat mass as the percentage of body weight.
BMI classification Displays LOW, NORMAL, HIGH, or VERY HIGH.
BMI is an internationally used index to show the body condition by checking the balance between the height and the weight. It is calculated by the following formula:
BMI: Body Mass Index= (weight (lbs) x 703) / height (in) / height(in)
BMI in metric = weight (kg) / height (m) / height (m)
