F138x FIXINST-Q Dual QCM dew point, pressure & temperature sensor

Measurement Range：-120 … 0 °Ctd

Characteristics

The F138x series integrates 3 sensors: temperature, humidity and pressure in a very compact space. It measures the dewpoint and simultaneously monitors the online pressure and outputs both the pressure dewpoint and the atmospheric dewpoint at the same time. QCM sensor technology is a revolutionary humidity measurement technology. Combined with the newly developed moisture sensitive material, it has excellent signal sensitivity in ultra-low humidity conditions and can measure humidity down to ppb level stably. Revolutionary auto-calibration circuit design automatically compensates for circuit drift caused by temperature, contamination, and aging, providing long-term stability and high accuracy measurements Innovative temperature compensation algorithm and multi-point temperature compensation calibration, greatly improving the sensor’s temperature drift and ensuring high-precision dewpoint measurement over a wide temperature range
