Testo 526 - Differential Pressure Measuring Instrument

Brand: Testo

Ideal for checking pressure in sensitive industrial processes, the testo 526-1 high precision differential pressure measuring instrument has a measuring accuracy of ±0.1% of the 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 ± 0.05% of the final value.

Two additional pressure and temperature probes can be attached.

The testo 526 is the differential pressure meter for industrial applications. Critical processes can be measured and monitored efficiently, with an accuracy of up to 0.1% or 0.05% of the full-scale value.
