Defender 510 / 520

Dry Gas Flow Calibrator

Product Name: Dry Gas Flow Calibrator

Model：Defender 510 / 520

 

The new generation of dry gas flow meters is a primary flow meter recommended and used in conjunction with numerous individual sampling pump manufacturers. It can be used in the fields of industrial hygiene, environmental protection, and various laboratories. It adopts the principle of dry piston movement, and can generate multiple consecutive readings with one press of a button. Compared with the traditional foam flowmeter, it is more convenient and fast to use. The 520 model has added the function of simultaneously testing temperature and pressure compared to the 510 model.
