The HygroPro is a loop-powered, intrinsically safe moisture transmitter for measuring the moisture content in gases and non-aqueous liquids in pipeline natural gas, petrochemical, power generation, pharmaceutical, process, and industrial applications. The HygroPro features an aluminum oxide moisture sensor, temperature thermistor, and pressure transducer built on a single probe mount to provide real time measurements for the calculation of parameters such as ppmv in gases, pounds per million standard cubic feet in natural gas, ppmw in liquids and percent relative humidity in addition to dew point temperature.

The HygroPro consists of the replaceable transducer element containing the moisture, temperature, and pressure sensors along with a display and six-button keypad for full programming of the display and analog (4-20mA) and digital (RS485) outputs. The intrinsically safe certified electronics housed in a Type 4X/IP67 enclosure allow the HygroPro to be installed directly in the hazardous location. All calibration data for the moisture and pressure sensors is stored on the replaceable transducer element eliminating the need for manual data entry when changing the element.

The DewPro MMY 31 is a cost effective loop-powered transmitter designed for "in-line" installation where trace moisture measurement is required. The MMY31 mounts directly in the gas stream for applications including glove boxes, environmental chambers and test chambers.

The DewPro MMY 30 is a loop-powered dew point transmitter for analyzing moisture content in dessicant air dryers, pipeline natural gas and industrial gases. The 4-20 mA output measures dew point temperature or ppm in gases at line pressure or atmospheric pressure.

HygroTrace Ultra-Low Moisture Transmitter measures the moisture content in the parts per billion (PPBv) range in nitrogen and argon gas for applications such as cylinder and tank filling, gas distribution systems in fabrication systems, and tool and machine manufacturing in the semiconductor and ultra-high purity gas (UHP) markets. With over 70 years of experience with aluminium oxide moisture sensors, GE Sensing developed a new aluminium oxide sensor, manufactured with modern semiconductor techniques, which uses a newly patented measurement technique to provide the sensitivity and speed of response in the PPBv range matched only by traditionally expensive analyzers. It is now possible to monitor multiple points of measurements for less than the cost of one analyzer and without installation constrictions. Its unique and innovative sensor measurement technique responds to wet up and dry down conditions in minutes minimizing moisture intrusion in your process.
