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.
