Product details
The Defender530 flow calibrator is a new generation of dry gas flow meter. It is a primary flow meter and is recommended and used in conjunction with numerous individual sampling pump manufacturers. Can be used in the fields of industrial hygiene, environmental protection, and various laboratories. It adopts the principle of dry piston motion, and multiple consecutive readings can be generated with one button press. Compared with the traditional foam flowmeter, it is more convenient and fast to use. The 520 and 530 models have added the ability to simultaneously test temperature and pressure compared to the 510.
