QTR series sensor is a simple and compact wall mounting indoor Air Quality sensor
providing a large screen readout of Co2, Temperature and Humidity. Suitable for residential,
factory or office building’s air quality monitoring. Using a sophisticated semi conducted chip for
sensing and converting the readings to RS485 digital signals for Bacnet MSTP or Modbus
protocols as well as providing voltage or current analog output signals for direct control of
equipment. Suitable for use with any BMS or PLC controllers for automation control. Optional in
touch screen models and varying output signals. There is a model to suit any application making
monitoring and control of an indoor space simple and effective.
