Testo 521-2 Differential Pressure Measuring Instrument is focused on exact differential weight estimations in cooling and ventilation innovation. It is magnificent for use in estimating the weight drop on channels and in checking fans and extractors. The estimating instrument is likewise appropriate for Pitot tube estimations in ventilation pipes or in-process air (in the 5 to 100 m/s go).

Applications: pneumatic, compressor and pump installations, valves, tanks and heating, ventilation, and air conditioning (HVAC) systems.
