Press Release Summary:
Using thermal conductivity sensors, Model AHT-200 measures moisture content at elevated temperatures up to +200Â°C with outputs of 0-5 V, 0-10 V, or 4-20 mA. It offers range of 0-130 g/mÂ³, with accuracy of Â±3 g/mÂ³, which corresponds to Â±2.3% RH at 35 g/mÂ³ at 60Â°C. Suited for harsh environments, washable transmitter recovers from deposits and condensation.
Original Press Release:
Absolute Humidity Transmitter
A new transmitter design, Model AHT-200, uses thermal conductivity sensors to measure moisture content at elevated temperatures up to +200°C. The unit outperforms conventional capacitive/resistance humidity sensors in harsh environments and it recovers from deposits and condensation. Washable and easy to clean. Useable with most gases. The range is 0 to 130 grams/m³; accuracy is ±3 grams/m³ which corresponds to ±2.3% RH at 35 grams/m³ at 60°C; output is 0-5V, 0-10V, or 4-20mA.
