Air conditioning systems are equipped with filters which prevent dirt from the outside air entering the indoor air. These filters are to be inspected regularly to make sure they are still fully functional. To do this, the pressure is measured in front of and behind the filter. The result is the differential pressure. If it is too high, the filter is contaminated and needs changing.
The testo 510 measures differential pressures in a range of 0 - 100 hPa. The differential pressure measurement is temperature-compensated for exact readings. The readings can be displayed in pascal over the entire measuring range. Magnets on the rear of the instrument allow hands-free work.
