The Michell Instruments Easidew PDP Dryer Portable Dew Point Hygrometer was developed to measure compliance when making quality assurance measurements on the dryer outlet before gas custody transfer occurs. It incorporates the latest Michell ceramic metal oxide and polymer technologies, providing reliable and repeatable pressurized moisture measurements with ISO 8573-1 air quality Classes.

Gas treatment dryers are technically specified at pressure dew points (PDP); this portable measures, stores, and downloads key gas-quality measurands including dew points between -100 and 20°C, line pressures up to 20 barg, ambient/process temperatures between -4 and 122°F, and real-time/date reference.

Designed to meet the needs of gas treatment engineers working remotely in harsh physical and electrical conditions, the Easidew PDP features a drop-tested case, heavy industrial certification, IP54 touchscreen display and front panel, and field serviceability with fast delivery of replacement spares. It offers two sensor technologies: Easidew metal oxide (-148 to 68°F dew point range) and SF82 polymer ultra-fast response (-76 to 140°F dew point range).
