F139C-Puri FIXINST-A Aluminum oxide high purity dew point sensor

Measurement Range：-120 … +20 °Ctd

Characteristics

F139C-Puri is a dewpoint measuring instrument specially designed for high-purity gas conditions. It uses FIXINST-A, an ultra-fast response aluminum oxide sensor with innovative moisture sensitive materials and processes. It has extremely high sensitivity and stability and can accurately capture small moisture changes in the medium, stable measurement of humidity as low as ppb level, providing accurate and reliable key data for gas analysis, quality control and process optimization. Revolutionary auto-calibration circuit design automatically compensates for measuring 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. The VCR process is used for connection, with high connection strength and good air-tight performance, is widely used for special gas or high purity gas pipelines.
