F108x FIXINST-A New-generation Al₂O₃ Standard Dewpoint Transmitter

Product Advantages：	Fast Response
Measurement Range：	-110 … +20 °Ctd

Product Overview

When the dewpoint of the measuring medium is below -40 °Ctd, the aluminum oxide sensor is the most accurate, responsive and long-term stable in comparison with other types of sensors. Meanwhile, it has excellent anti-pollution ability Revolutionary auto-calibration circuit design automatically compen sates 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
