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.
