Defender type dry flowmeter

DefenderIt is a new generation of dry gas flowmeter, belonging to the first stage flowmeter, recommended and used by a large number of individual sampling pump manufacturers. Using the principle of dry piston motion, multiple consecutive readings can be generated with one button press. Compared with the traditional foam flowmeter, it is more convenient and fast to use. Used for calibration of air sampling pumps for industrial hygiene and occupational health.
