Model #137-C3-S10AP-MR

Measuring set, dew point

Ian air sample is directed into the sensor, dew point ml-644/amq-34 whichcontains a thermoelectrically-cooled mirror surface and an optical dew pointsensing configuration; the control-power supply c-9352/amq-34 supplies power to the cooler, reducing the mirror temp. Until dew forms; the optical sensing configuration controls a servo loop that maintains the mirror temp. At this point, and the indicator, dew point temp. Id-1890/amq-34 displays the dew point temp
