Product Introduction

TG9 Series Duct TypeCarbon Dioxide Transmitter

• TG9 SeriesCO2 Transmitteris specifically designed for measuring CO2 concentration in HVAC ducts.
• The CO2 detection element uses an NDIR non-dispersive infrared self-diffusion sensor with self-calibration function to ensure long-term stability, with a service life of up to 15 years.
• Temperature and humidity options use high-precision digital temperature and humidity sensors.
• Provides one or three 0~10VAC/4~20mA analog linear outputs
• Provides Modbus RS485 communication interface option.
• Optional LCD backlit display showing all measured values
• Simple and compact structural design, with detachable and cleanable or replaceable filter for dust protection to avoid external contamination affecting measurement values, making measurement more accurate.
• Provides split sensor probe model TG5 series with 2-meter connection cable for special places such as incubators and food storage
