DT282

 Digital Relative Humidity and Temperature Transmitter for Duct Installation
The DT282 relative humidity transmitter includes 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 down-time is minimized.






Product Features

  • Analog and digital output standard
  • Based on the interchangeable Hygrosmart module
  • Analog output signals selectable through software
  • Metric or imperial measurement units selectable through software
