Product Specification

Carbon Dioxide Duct Probe Transmitter
TG9xx6x


  • The TG9 is a CO2 transmitter designed for detection carbon dioxide in air ducts of HVAC systems.

  • The CO2 sensor uses the Non-Dispersive Infrared Technology (NDIR) with the patented self-calibration system to guarantee the long term stability and up to 15 years life time.
  • Optional  temperature and humidity detection with a high accuracy digital combined sensor, it provides a digital interface and outstanding full range linearity.
  • T he one or three analog 0-10V or 4~20mA outputs are selectable by jumpers.
  • Modbus RS485 communication interface option.
  • With or without LCD
  • Smart and skillful design for structure, with a  special demountable and replaceable filter to avoid pollution and influence of measurement.
  • Provide a split type model with an external sensor probe, 2 meter connection cable, is used in incubators or food stores etc.
