Aluminium Oxide Moisture Sensor
The AquaXact 1688 is a rugged ultra-thin film aluminium oxide moisture sensor that enables fast and accurate dew point and ppm H2O measurements of moisture in a wide variety of gas phase process applications. Not only is it a standalone 4-20mA transmitter, but it is also able to be remotely interfaced to the AquaXact 1688 digital controller or any of the Servomex next-generation products. Such as the MonoExact DF310E which has the optional Oxygen % and ppm measurement capabilities.
Replacement Sensor Element: The Al2O3 thin film sensor tip can be replaced by the user and the associated calibration file loaded into the transmitter using the controller, eliminating the return-to-factory calibrations. Yearly field calibration adjustments require only a single gas standard.
