testo 526-2 - Differential pressure measuring instrument 0 to 2000 hPa (accuracy ±0.05% of f.v.)

testo 526-1
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.
  • Temperature-compensated differential pressure sensor
  • Multi-point and timed mean calculation
  • Freely selectable measuring rate for recording measurement data
  • 2 additional probe inputs for the attachment of optional pressure and temperature probes
The testo 526 is the differential pressure meter for industrial applications. Critical processes can be measured and monitored highly efficiently, with an accuracy of up to 0.05% of the full-scale value.
