F303x Dewpoint & Pressure Multi-parameter Portable Monitor

Product Advantages: Portable Measurement
Measurement Range: -110 … +60 °Ctd Optional
Product Overview

The F303x series dewpoint meter can integrate a variety of the most advanced humidity sensors: polymer film capacitive sensors, ultra-fast response aluminum oxide sensors with innovative moisture sensitive materials and processes, and dual resonance QCM sensors with sensitivity at ultra-low dewpoint. These sensors provide F303x with the ability to accurately measure a wide range of dewpoints from -110 to +60 °Ctd 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
