It is an innovated portable battery densitometer designed for measuring the optical density (blackening) of technical radiographs.
MD20 digital densitometer
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
