Testo 521-1 Differential pressure measuring instrument


Testo 521-1 differential pressure measuring instrument is focused on correct differential weight estimations in cooling and ventilation advancement. It is unimaginable for use in estimating the weight drop on diverts and in checking fans and extractors. The assessing instrument is in a like manner suitable for Pitot tube estimations in ventilation conductors or in-process air (in the 5 to 100 m/s broaden).

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