tSENSE is an advanced and versatile 3-in-1 transmitter designed for installation in the air-conditioned zone. It measures CO2 concentration, temperature and humidity in the ambient air accurately without need for additional compensation ─ true read. The data transmits to a BMS system or stand-alone controller using industry standard output signals and communication protocols. It is flexible in design with display, temperature control and combination of humidity control optional.Complies with ASHRAE standard 189.1 (±50ppm @ 1000ppm of measured CO2 value)

Key benefits

-Three sensors in one housing
-Colour touch display with possibility of customizable GUI
-Flexibility - Temperature and/or Humidity optional
-Improved housing design for effective measurement
