TESTO 512 Differential pressure meter for 0~20 hPa

The testo 512 with a measuring range from 0…20 hPa can be used to help you carry out quick and easy filter checks when performing differential pressure checks on ventilation and air conditioning systems. Differential pressure measurements are carried out to determine whether filters still work properly or whether they are used up and clogged and need to be replaced.

The differential pressure meter is ideal for carrying out pitot static tube measurements in air ducts at very high air flow speeds or when the air stream is strongly polluted. The compact, rugged meter shows both the pressure as well as the air flow speed and has a measuring range from 5 to 55 m/s.
