GTQ-V - Temperature and CO2 sensor, wall mounted

GTQV is a combined temperature and carbon dioxide sensor for indoor wall mounting. 

The encapsulation is designed to give as short a time constant as possible for temperature changes and a good through flow for carbon dioxide measurement. 

  • Is intended for use together with room climate controller RCC, lab climate controller LCR or an active supply air diffuser. 
  • Is primarily intended for controlling the carbon dioxide concentration in the ventilated room, with an option of additional room temperature measurement. 
  • The active supply air diffusers TTC and VTD and laboratory climate controller LCR are normally already equipped for room temperature measurement. 


The combined sensor gives a 2-10 V output signal for the range 400-2000 ppm carbon dioxide, while the temperature sensor gives a 0-10 V output signal for the range 12-43ºC.
