This intelligent analytical scale has 24 chrome-plated electrodes that provide permanent skin contact during measurement; thus making it possible to determine body fat and fluids. In order to assess the collected values, the analytical scale requires additional information (such as body height, gender, body type), which can be easily entered using the control panel before measurement. The seca 804 is also able to determine the patient's BMI by entering the gender and height. The analytical scale can store personal data for up to 4 different people. It can also weigh in "guest mode."
