The Model AHT-200 absolute humidity transmitter uses thermal conductivity sensors to measure moisture content at elevated temperatures up to 200°C. It is said to outperform conventional capacitive/resistance humidity sensors in harsh environments, and it can recover from exposure to deposits and condensation. Its range is 0–130 g/m3 with an accuracy of ±3 g/m3, which corresponds to ±2.3% RH at 35 g/m3 at 60°C.
