The "Harpenden" Anthropometer is a counter recording instrument which can be effortlessly operated from the tips of its branches. Its user can, therefore, by means of his free finger-tips actually feel his way to his desired measuring points in order to obtain a degree of accuracy not possible with conventional anthropometers.
Specification
This instrument gives a direct and accurate reading, to the nearest millimetre, over a range of 50 mm to 570 mm. It is constructed mainly of light alloy anodised to its natural colour. Its sliding member operates via miniature ball-bearing rollers in order to ensure a movement which is free yet without cross-play.
Each instrument is supplied in a well made carrying case, complete with straight and recurved branches, a spare counter and beam extensions for the measuring of heights of up to two metres (When using these a constant should be added to the counter reading).
Weight in case: 2.8 kg approx.
