PTS MD20 Digital Densitometer

It is an innovated portable battery densitometer designed for measuring the optical density (blackening) of technical radiographs.
Advantages of the device
very high accuracy thanks to the use of an integrated circuit with the ability to logarithm in four decades with an error of 0.2 %
zeroing at any illumination
one of the smallest densitometers on the market
it is possible to measure a value of up to 4D with sufficient illumination
favourable price
