Model SADPµ Dewpoint Meter, the world's leading hygrometer, is now manufactured by Alpha Moisture Systems under a licensing agreement from SHAW.

Through application of advanced microprocessor electronics, the original work-horse of industrial hygrometry for over 25 years has been brought up to date for the millennium.

Designed to operate at atmospheric pressure, the Model SADPµ is available in various ranges. The large, easy to read analogue indicator is scaled in ºC dewpoint, ºF dewpoint and corresponding parts per million range. The low 0-10ppm(v) range is switch selectable to read over the full scale. Model SADPµ is fully self contained and is certified intrinsically safe for use in hazardous environments to ATEX II 1G.

The unit is supplied ready for use with batteries installed, calibration certificate traceable to National and International Humidity Standards, two metres of PTFE sampling hose, instruction manual and a specially designed heavy duty leather case with shoulder strap for use in hazardous areas.
