Product Details

The GPM Anthropometer is world renowned for its precision, durability, and ease of use and is frequently cited in medical journals, textbooks, & studies. The Anthropometer is an extremely versatile instrument suitable for measuring nearly any linear dimension of the human body.

The Anthropometer consists of four interconnecting metal tubes, whose surfaces are engraved in millimeter intervals.  With the four sections connected, the measuring range is from 0 to 2100 mm. The upper two sections of the GPM Anthropometer can also be used as a sliding beam caliper with a measuring range of 0 to 950 mm.

Measurements are taken via the measuring branch holder, which slides up and down the interconnected tubes.  The scale reading window on the branch holder enables the operator to read the numerical value easily and accurately to the nearest millimeter.

The GPM Anthropometer is also referred to as the Martin anthropometer, for its inventor Rudolf Martin.

GPM offers several accessory add-ons for the Anthropometer, including a canvas carrying bag, recurved metal branches, a baseplate, and an auricular height needle.
