Density meter for Radiographic Testing:

Density meter
The D001 series densimeter for radiographic testing developed by our company is domestically high-tech computerized product with high quality. The accurate reading, favorable stability and convenient operation are its obvious features. D001 series density meter can be widely used in various industries, including nondestructive testing (NDT), printing and medical treatment. The inclusive density film with the machine is used for calibration.
