The HVAC Meter / HVACR Tester is a small and handy measuring device for determining the differential air pressure. The pressure meter has a measuring range of ±5000 Pa. The pressure meter is connected via two hose connections with a diameter of 8 mm. After switching on, the pressure meter shows the differential pressure directly. The measured value can be displayed in 11 different pressure units. The pressure meter is used, for example, in ventilation and air conditioning technology or in educational institutions such as technical colleges and universities.
In addition to the normal display of measured values, the HVAC Meter / HVACR Tester can also display the smallest, largest and average measured values. This makes the pressure meter easier to analyze the measured values. To save the batteries, the pressure meter switches itself off automatically within five minutes.
