Differential Pressure Measuring Instrument (0.2 % Of F.v.)-Testo 521-1

The testo 521-1 differential pressure measuring instrument is targeted at precise differential pressure measurements in air conditioning and ventilation technology. It is excellent for use in measuring the pressure drop on filters and in checking fans and extractors. The measuring instrument is also suitable for Pitot tube measurements in ventilation ducts or in process air (in the 5 to 100 ms range).
The differential pressure measuring instrument has an integrated temperature-compensated differential pressure sensor which measures with an accuracy of 0.2 % of f.v. In addition, you can attach up to 2 further optional probes to the measuring instrument. This means you can flexibly adapt the differential pressure measuring instrument to your application. You have the choice of the following probes:
Differential pressure probes
Absolute pressure probes
Relative pressure probes
Temperature probes (e.g. surface probes or immersion and penetration probes)
