Dew Point Transmitters

Process Sensing Technologies

Our range of dew-point sensors are easy to install and maintain. They measure dew point, moisture content and trace moisture in both gases and hydrocarbon liquids. Typical applications include monitoring compressed air dryers to maximize energy savings, protecting process equipment from moisture corrosion/contamination and monitoring controlled atmospheres in glove boxes. Available with a sensor exchange program to minimize maintenance time, they are reliable and cost-effective.

Chilled Mirror Reference Hygrometers

Process Sensing Technologies

Chilled mirror dew-point hygrometers provide highly accurate and stable measurements of trace moisture and humidity. The precision chilled-mirror reference hygrometers are sensitive to changes in very low moisture concentrations (less than 5 ppbV). Industrial dew-point hygrometers are capable of withstanding high temperatures and hot saturated gases while still providing highly stable and accurate humidity measurements. As well as being used as reference instruments in calibration laboratories they are used for precise environmental control in research laboratories, testing automotive emissions and controlling metallurgical processes.
