Temperature and Humidity Meter

A must have accessory for complying with NABL accreditation requirements for calibration of air pollution monitoring instruments.

Measurement of Relative Humidity (RH) and temperature is required extensively in Air Pollution Monitoring. The various standard calibration procedures approved by NABL mandate the measurement of relative humidity and temperature at operating conditions for applying the necessary corrections to the measurements.

Available Model : PSI-RHT 1

Range :

Relative Humidity	0 – 100 %
Resolution	40 to +60^oC

Application :

Applying necessary corrections to measurements made by air pollution monitoring instruments at operating and atmospheric conditions.

Physical Design Highlights

PSI-RHT-1 utilizes a high accuracy precision solid-state sensor probe and a compact microprocessor based electronic unit. The electronic unit processes the signal from the sensor and indicates RH and temperature measurements on its display unit.

It can be used for measurement either in open atmosphere or can be inserted in to any closed chamber.

The display indicator works on 5 VDC which is provided through an ac mains adaptor.

Salient Features :

Simultaneous measurement of RH and Temperature
Useful for open atmosphere as well in a closed chamber.
Microprocessor based Design
Excellent accuracy and Resolution
Backlit Alphanumeric Display
Compact and lightweight
