Range -80 degrees c. dew point to room air.
Certified intrinsically safe.
Quick Moisture readings on flowing dry air or gas.

Easily portable, ready for spot checks or continuous use, this battery powered hygrometer indicates both dew point temperatures and water vapour to less than one part per million, on the large meter dial. As the reading is specific to water vapour, calibration is accurate for different gases. Accuracy is guaranteed to better than one part in a million of moisture in very dry air or gas.

The self extending head allows up to 20 litres a minute flow for clearing the air supply pipe work without wetting the test chamber. Note the absence of knobs, calibrating, cooling, and servicing as required by some other methods, and the automatic dry down measuring head which ensures quick response from the sensor.

The heart of the meter is a Shaw molecular sieve moisture sensor with a gold internal filter and gold plated exterior, a jewel of a sensor in fact with a rapid one second response time from dry to wet.(99%) Flow rate has no effect on the accurate measurement.
So simple to use, blocking the outlet with a finger for a moment raises the measurement head.
