Michell Instruments Easidew PDP Dryer Portable Dew Point Hygrometer Easidew M12 Digital Dewpoint & Temperature Transmitter: -100 to 20°C DP 1/8” BSPT adapter to 1/4" Swagelok 2m PTFE sample tube 6mm O/D thick-walled

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. The dryer portable 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:

• Dew points between -100 and 20°C
• Line pressures up to 20barg
• Ambient/process temperatures between -4 and 122°F
• Real time and date reference

The Easidew PDP has been designed to meet the need of gas treatment engineers who use the spot-checking tool remotely in harsh physical and electrical conditions, and who need a reliable unit that does not fail on site. This is supported by a drop-tested case, heavy industrial certification, IP54 touchscreen display and front panel, and field serviceability with fast delivery of replacement spares.

The majority of moisture compliance testing in compressed air is undertaken on Class 1 to 4 dryers. The Easidew PDP Portable offers two sensor technologies to meet these needs:

• Easidew metal oxide -148 to 68°F dew point range
• SF82 polymer ultra-fast response -76 to 140°F dew point range
