InBody 380 Body Composition Analyzer

The InBody 380 Body Composition Analyzer reads fat, muscle and water at five body segments in about 30 seconds. A small painless current runs at 5 kHz, 50 kHz and 500 kHz, each read at both arms, both legs and the trunk, for 15 impedance measurements. Phase angle, ECW/TBW and soft lean mass arrive together on the 380, where the InBody 270S reports phase angle alone and the 580 repeats all three by segment. ECW/TBW is the share of body water outside the cells, and soft lean mass is lean tissue minus bone mineral.
