  • Temperature-compensated differential pressure sensor
  • Multi-point and timed mean calculation
  • Recording of measurement data with freely selectable measuring rate
  • 2 probe inputs for pressure and temperature
    • 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 is the differential pressure meter for industrial applications. Critical processes can be measured and monitored efficiently, with an accuracy of up to 0.1% of the full-scale value.
