You can carry out all the necessary tests on gas heating systems as well as water and gas pipes with the testo 312-4 electronic differential pressure measuring instrument. Preset measuring processes, for example for load and tightness tests as well as serviceability testing on gas pipes, provide you with ideal support for your work.

The high-precision testo 521-1 differential pressure measuring instrument is ideal for accurate differential pressure measurements in air conditioning and ventilation technology, for instance for pressure drop on filters, checking fans and extractors or for Pitot tube measurements.

The high-precision testo 521-2 differential pressure measuring instrument is ideal for accurate differential pressure measurements in air conditioning and ventilation technology, for instance for pressure drop on filters, checking fans and extractors or for Pitot tube measurements.

Differential pressure measuring instrument 0 to 2.5 hPa

Ideal for checking pressure in sensitive industrial processes: the testo 526-1 high-precision differential pressure measuring instrument with a measuring accuracy of &plusmn; 0.1% of final value. It also has two probe inputs for additional pressure and temperature probes.

The testo 526-2 high-precision differential pressure measuring instrument is ideally suited for checking pressure in sensitive industrial processes, thanks to a measuring accuracy of &plusmn; 0.05% of final value. Two additional pressure and temperature probes can also be attached.

The desktop mains unit is versatile to use thanks to its international connection options.
