Experience Precision and Durability with the Modbus-Integrated Duct Carbon Dioxide Transmitter

The CO2D-series Duct Carbon Dioxide (CO2) Transmitter is an advanced device designed for durability and efficiency. It is equipped with a maintenance-free NDIR sensor, ensuring reliable performance without the need for regular upkeep. This transmitter offers a flexible measuring range of 400-2,000 ppm, 0-2,000 ppm, 0-5,000 ppm, and 0-10,000 ppm, with an additional selectable range of 0-1,000 ppm available upon request using a DIP switch.

One of the remarkable features of the CO2D-series is its output capabilities, providing options of 0-10 Vdc, 2-10 Vdc, 4-20 ma, 0-5 Vdc or 1-5 Vdc, with both single and dual CO2 outputs available. This makes it adaptable to various requirements and applications.

Designed for longevity, the CO2D-series Duct Carbon Dioxide Transmitter boasts an impressive estimated operating life of 15 years. It also incorporates an Automatic Baseline Calculation (ABC) feature, enhancing its accuracy and dependability. Its accuracy rate stands at 70 ppm +3 % reading, ensuring precise measurements every time.

The CO2D-series Transmitter, with its 24 Vac/dc power supply, is an ideal solution for a wide range of settings and applications. It has been specifically engineered to enhance indoor ventilation control and monitor CO2 levels in various environments such as offices, conference rooms, cinemas/theatre halls, exhibition halls, restaurants, and shopping malls. The CO2D-series Duct Carbon Dioxide Transmitter, with its superior features and specs, marks a notable advancement in CO2 monitoring, making it the ideal choice for industrial applications.
