You are choosing between a professional body composition analyser<\/strong> and a home body composition scale<\/strong>, and both carry the InBody name. On one tab is the InBody 770S<\/a>, a clinical-grade machine that hospitals and premium gyms install in a permanent corner. On the other hand is the InBody Dial H40<\/a>, a sleek home scale that fits next to your bathroom basin. Both use BIA. Both measure body composition. So which one do you actually buy?<\/p>\n\n\n\n

The honest answer depends on a single question: what will you do with the data?<\/strong> If you are running a clinic and a single number will guide a clinical decision, you need professional-grade accuracy. If you are an individual tracking your own progress over months, you need consistent measurement, not absolute precision. These are different jobs, and InBody builds different machines for them. This guide will help you pick the right tier professional or home without overspending or under-buying.<\/p>\n\n\n\n

What “professional” and “home” actually mean (technically)<\/h2>\n\n\n\n

InBody’s professional range, the 270S, 380, 570, 770S, and 970S, uses Direct Segmental Measurement Multi-Frequency BIA (DSM-BIA)<\/strong>. Eight tactile electrodes measure your arms, legs, and trunk independently. Most professional models run 4\u20136 frequencies (1, 5, 50, 250, 500, and 1000 kHz on the 770S and 970S), which lets the device distinguish intracellular from extracellular water, detect inflammation, and produce phase-angle readings.<\/p>\n\n\n\n

The home Dial range H40, H30, H20 uses a simpler 4-point tetrapolar BIA setup. You stand on the platform, hold a position, and the device estimates whole-body composition. There is no segmental breakdown of left arm versus right arm. There is no multi-frequency analysis. It runs single-frequency at 50 kHz, which is enough for trustworthy trend tracking but not for clinical interpretation.<\/p>\n\n\n\n

The accuracy gap matters. The professional InBody range correlates 98.4% with DEXA scans in peer-reviewed validation studies<\/a>. The home Dial range correlates well for trend tracking, but absolute single readings carry a margin of 2\u20133% body fat in either direction. For most individuals tracking themselves week to week, that margin is invisible. For a hospital making a sarcopenia diagnosis or applying the WHO body composition criteria<\/a>, it is not.<\/p>\n\n\n\n

When to choose a professional InBody<\/h2>\n\n\n\n

Buy a professional InBody (270S, 380, 570, 770S, or 970S) if any of the following describes you:<\/p>\n\n\n\n
