Duct CO2 Sensor

This duct mounted CO2 sensor uses NDIR non-dispersive infrared technology for CO2 concentration measurement. In addition to the measurement channel, our product also adds a reference channel, and the measurement data is more accurate, which is better than most co2 sensors on the market.It is widely used in the monitoring of carbon dioxide concentration in the return air duct and the control of outdoor air intake.

Overview - Duct mounted CO2 sensor

Our duct mounted CO2 sensors are designed to measure carbon dioxide levels in extraction ductwork. Various signal outputs, such as: RS485, 4-20mA, 0-5V, and 0-10V. The RS485 duct CO2 sensor has an automatic calibration function. Optional LCD display for easy access to values even in dim light. The internal anti-interference circuit is designed, which can withstand various strong electromagnetic interference such as on-site frequency converters. This duct mounted CO2 sensor can be used to measure CO2 levels in the ducts of ventilation and air conditioning systems. Improve room comfort and optimize energy consumption by controlling ventilation.

Duct CO2 sensor features

1. This duct mounted CO2 sensor probe is stainless steel, which is corrosion-resistant and greatly improves the service life. The sensor housing is made of high-strength waterproof material and can be used in outdoor environments.
2. The measurement range is 0-5000ppm, other ranges can be customized.
3. With automatic calibration function. After long-term use, take the rs485 duct mounted CO2 sensor to a clean outdoor environment and wait for a while to complete the automatic calibration.
4. Comes with temperature compensation, less affected by temperature.
5. Built-in high-precision non-dispersive infrared sensor elements, accurate measurement and sensitive reflection.
6. 10-30V wide voltage power supply, there are two types with display and without display.
7. Duct co2 sensors are widely used in building automation systems to control ventilation equipment in industrial and commercial applications.
