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.   Product Description HygroTrace Transmitter features an integral backlit display and keypad electronics package mounted on a “flow-through” tee sample cell that can be installed directly into the process stream or on a bypass leg of a gas distribution network. HygroTrace measures from 0 to 100 PPBv moisture in nitrogen or argon gas with trending analysis beyond the calibrated range. The accuracy of the measurement is ± 20% of reading or ± 5 PPBv, whichever is greater. HygroTrace offers unprecedented speed of response for aluminum oxide sensors in this very low range with a response time of less than 20 minutes to 95% of a 25 PPBv step change. HygroTrace features analog (4-20mA) and digital (RS485) outputs. HygroTrace’s compact VCR sample tee is designed for installation where space is limited and requires no custom machining.
