DT269 Duct Mount Digital Relative Humidity and Temperature Transmitter

The DT269 transmitter has a I7000 Hygrosmart module. Thanks to this solution, the sensor can be changed on site quickly and simply, providing greatly reduced maintenance costs. The transmitter does not need recalibration after the sensor is changed.







Product Features

  • Designed for accurate measurement in a controlled environment
  • Based on the interchangeable Hygrosmart module
  • Temperature output scaling configurable on request
  • Linearization for a specific isotherm on request
