AUTOMATIC DEWPOINT METER
A Portable Hygrometer For Rapid Moisture Checks
Or Continuous Use On Flowing Gas Or Air
The only dewpoint meter are ready for instant moisture checks down to one part per million of water vapour in flowing dry air or gas.
This robust and easy to use hygrometer has high capacitance sensor for rapid moisture checks or continuous use on flowing air or gas. With a five second user check, the sensors have a fine gold permeable filter. The large clear moving coil meter dial is accurately marked with dewpoint temperature and parts per million of moisture. Flow rate makes no difference to the dial readings.
Simple to use - the head (test chamber) is filled with very dry molecular sieve desiccant and can be extended by blocking the outlet with a finger for a moment when air flow is present. Just read the dial. Press down the head to pre-dry the space for the next test and switch off.
Intrinsic safety certificate is standard. After your dewpoint meter has passed our three weeks of careful laboratory checks which are of course traceable to the National Physical Laboratory and our quality control to ISO 9002, new seven year batteries are fitted and the dewpoint meter is ready for dispatch and your immediate use.
