G01 (CO2 Sensor)

New Tondgy G01 CO2 monitor/alarm is used to monitoring room CO2 level, as well as room temperature and humidity It provides one on/off output to control a ventilator with four CO2 levels presetting. Especially i t provides both buzzer alarm and three colors backlit switching alarm.

  • Design for real time monitoring room carbondioxide (CO2) level
  • NDIR infrared CO2 sensor inside with special Self Calibration System. It makes the CO2 measurement more accurate and more reliable in use.
  • More than 10 years lifetime of CO2 sensor
  • Temperature and humidity monitoring
  • Three color (green/yellow/red) LCD backlit indicating ventilation optimal/moderate/poor based on the CO2 measurement
  • Two alarm ways : buzzer alarm and back-light Colours switch
  • Provide optional 1 x relay output to control a ventilator
  • Easy touch button for operation
  • High quality with the perfect appearance, best choice for home and office
  • 220VAC or 24VAC/VDC power selectable; power adapter available; desktop and wall mounting type available
  • EU standard and CE approval
