Product Overview
The Online Carbon Dioxide (CO₂) Monitor is a high-precision gas detection device designed for real-time monitoring and data logging of CO₂ concentration in various environments. It uses a pump-suction sampling system combined with a high-accuracy CO₂ sensor to ensure stable and reliable measurements.
Equipped with a 7-inch industrial touchscreen, the device provides real-time data display and easy access to historical records. It is suitable for a wide range of applications, including environmental monitoring and safety management across different industries.
Working Principle
The system uses an active pump-suction method to draw ambient air into a built-in pretreatment unit. The gas passes through a flow meter and dust filter before entering the high-precision CO₂ sensor for analysis.
The monitor integrates automatic detection, self-diagnosis, and alarm functions. It also supports 4G/5G wireless communication and the HJ/T 212 protocol, allowing real-time data transmission to remote platforms for continuous and reliable monitoring.
