The Hot Body Fat Monitor is a handheld device that allows you to easily monitor your body fat percentage and BMI. It is wireless, lightweight, and portable, making it convenient to use wherever you go. The device calculates your body fat percentage using five data points: height, weight, age, gender, and the resistance value between your palms. The large liquid crystal display makes it easy to read the results. Setting up your personal profile and storing it in the device's memory makes monitoring quick and easy. With a 9-person-profile memory, each member of your family or team can track the success of their individual exercise routines. The device measures not only your body fat percentage and BMI, but also your body shape and basic metabolism. It can provide accurate results in just 6 seconds. The Hot Body Fat Monitor is not only a recommended household instrument, but also a perfect gift for relatives and friends. Please note that for special groups such as athletes and pregnant women, the body fat percentage and BMI may not accurately reflect obesity.
