The InBody 270 is a portable yet accurate body composition analyzer that uses only impedance to determine body composition results within 15 seconds. No statistical data or empirical equations are used or required to predict body composition. The InBody 270 measures and records a user’s weight, skeletal muscle mass, and percent body fat from the last eight tests to track progress over time. No dunking. No pinching. No discomfort. Simply stand on the device and hold the hand electrodes to test. **Comes with a case and data sheets as well* Here is a link that explains the inbody a bit more https://inbodycanada.ca/products/inbody-270-body-composition-analyzer-2/
