Testo 521-1 - Differential Pressure Measuring Instrument

The testo 521-1 differential weight estimating instrument is focused at exact differential weight estimations in cooling and ventilation innovation. It is incredible 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 conduits or in process air (in the 5 to 100 m/s extend).


Tax /GST included

The Differential Pressure Measuring Instrument has an incorporated temperature-repaid differential weight sensor which measures with an exactness of 0.2 % of f.v. Furthermore, you can append up to 2 assist discretionary tests to the estimating instrument. This implies you can adaptably adjust the differential weight estimating instrument to your application. You have the decision of the accompanying tests:
