The 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.
【Features】
- Adopt NDIR non-dispersive infrared CO2 sensor and chip type temperature and humidity sensor.
- TFT color display screen can display temperature, humidity and carbon dioxide value.
- You can choose to output IAQ information as RS485 signals in different formats such as BACnet MS/TP, Modbus RTU or AIRTEK EIMnet, or as analog signals in different types of 0~10V and 4~20mA.
- The visual deviation value of compensation temperature/humidity/carbon dioxide can be set.
- With a color icon to display the current air quality status function.
- It has an alarm sound effect to prompt indoor personnel with a sound when the air quality is poor.
- The set point of CO2 alarm trigger can be adjusted according to different applications.
- It has a BO dry contact output, which can be interlocked when a CO2 alarm occurs.
- When reading IAQ information through communication, AO*3 & BO can also be set as a remote output control.
- You can choose different display languages such as Simplified Chinese/Traditional Chinese/English.
