Defender dry gas flowmeter

Defender dry gas flowmeter

• 1、 Product Introduction:
  Defender510/520/530+is a new generation of dry gas flowmeter, which is a primary flowmeter. Can be used in the fields of industrial hygiene, environmental protection, and various laboratories. It adopts the principle of dry piston motion, and multiple readings can be generated with one button press. The 520 model has added the ability to simultaneously test temperature and pressure compared to the 510. Defender530+, the combined model of Defender530 and Definer220.
