Minco 1% and 2% Wall, Duct and OSA Humidity Transmitters HT829, HT839

Minco 1% and 2% Wall, Duct and OSA Humidity Transmitters

 

The Minco Model HT829 Relative Humidity Transmitter measures 0% to 100% RH over a range of -10° to 185°F (-23° to 85°C). The standard two-wire, 4-20 mA output provides low-cost space, duct, and outdoor monitoring or process and industrial building control. A temperature sensor built into the integrated circuit provides temperature compensation over the full temperature range. The HT829 Series is field-rangeable for field recalibration. These transmitters are proven performers for use in Building Automation Systems, BAS, and HVAC applications.
