Description
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 m/s range).
Additional Details
Key Advantages
- Differential pressure probes
- Absolute pressure probes
- Relative pressure probes
- Temperature probes (e.g. surface probes or immersion and penetration probes)
- The practical features of the testo 521-1 differential pressure measuring instrument
