Differential pressure measurement of the cleanroom

2 products or recommendations for Differential pressure measurement of the cleanroom
  • testo 521-3 - Differential pressure measuring instrument 0 to 2.5 hPa

    Order-Nr. 0560 5213

    The testo 521-3 high precision differential pressure measuring instrument easily determines even the smallest differential pressures (up to +2.5 hPa). Its high accuracy and a resolution of 0.1 Pa make the instrument ideal for differential pressure measurements, in clean rooms, or for flue inspections.
    • Integrated temperature-compensated differential pressure sensor with accuracy of up to ± 0.5 Pa

    • Calculation of the flow velocity and the volume flow via Pitot tube (optional)

    • Direct zeroing of the display values of pressure probes

    • 2 probe inputs for additional pressure and temperature probes
       

  • testo 420 - Differential pressure measuring instrument

    Order-Nr. 0560 0420

    Use the CEC compliant testo 420 differential pressure measuring instrument to carry out simple, efficient tests on filters. You can also use this instrument in conjunction with a pitot tube to easily measure flow velocity and volume flow in ventilation ducts
    • Differential pressure measurement, useful for checking filters in air conditioning and ventilation systems

    • Calculate flow velocity and volume flow using an optional pitot tube

    • Live data feed integration now available with the MeasureQuick App

    • Match with a Testo CEC compliant air flow capture hood to measure volume flows at supplies and returns (0563 4200)
