Combo RHT Instrument

Handy Combo Tool for Calibration Laboratories

Available Models : PSI-RHT-1 M and PSI-RHT-1 B

Relative humidity and temperature measurements are required extensively in Air Pollution Monitoring. Many calibration procedures require the measurements to be carried out at operating conditions. This in turn mandates the measurement of relative humidity and temperature in the laboratory.

Combo RHT Instrument

Salient Features :

  • Measures Relative Humidity & Temperature
  • Microprocessor based Design
  • Excellent accuracy & Resolution
  • Panel mountable / Table Top
  • Backlit Alpha-numeric Display
  • Compact & Light weight

Physical Design Highlights :

While PSI-RHT-1M is a mains operated instrument, PSI-RHT-1B is battery operated. The two models are similar in all respects except the source of power. Accordingly the two models are referred to PSI-RHT-1 in the rest of this document.

PSI-RHT-1 is a compact, panel mountable / table top instrument. It utilizes a precision solid-state Rotronic make sensor probe and a compact alpha-numeric display unit for viewing the RH and temperature simultaneously. It permits the user to keep the probe open to the atmosphere for measurement RH and temperature of the operating conditions. Alternatively, the probe can be inserted in to any chamber to measure these parameters. The display indicator works on 5 VDC which is provided through an adaptor.
