DT282

 Digital Relative Humidity and Temperature Transmitter for Duct Installation
DT282 relative humidity transmitters include the interchangeable HYGROSMART module. The interchangeable module lets you recalibrate the transmitter simply by replacing the sensor head with the HYGROSMART module. As a result, maintenance costs are greatly reduced and machine down time is minimized.
