The DewStar Series S-3S/M Chilled Mirror Hygrometer is designed to provide accurate, reliable dew point measurement using the new ACCU-STAR mirror maintenance feature, the company says. It measures dew point by controlling the temperature of a Rhodium-plated mirror at the dew point temperature using a digital control algorithm. Its remote monitor can display two selectable measurements, while outputting two selectable analog outputs, one selectable alarm point, and any combination of selected measurements on a serial port, says the company.
