The 070-8-0002 tSense CO2 + RH/T (formerly known as the SE-0034/0035) is an attractive, wall-mounted carbon dioxide concentration, temperature, and relative humidity transmitter. It is available with or without an LCD color touch screen display.

  • CO2, Temperature, % Relative Humidity
  • Easy Configuration via LCD Touch Screen
  • All Industry-Standard Outputs

With a display, the tSense can show you the CO2, temperature, or %RH levels in real-time. With a touch you can program the tSense display model to change color when the CO2, temperature or %RH levels get too high, or you can view graphs of CO2, temperature or %RH for the previous day or week. All settings can be controlled with a secret pin number you enter during setup.

With or without a display, both tSense models feature several industry-standard output options including 0-10VDC for each of the 3 parameters, NO and NC relays, and Modbus protocol. All options can be configured with free UIP software.
