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
