Product Description

Overview

 CL-2202
   The CL-2202 Malodorous Gas Online Monitoring Station enables round-the-clock, continuous, and automatic monitoring of atmospheric pollutants. It records historical data in real time, accurately reflecting the status and trends of malodorous gas pollution in the air. This system integrates hydrogen sulfide ( H2S ) and ammonia (NH3) sensors, with the flexibility to expand support for additional malodorous gas sensors. Its built-in RTC function ensures precise timestamping of monitoring data (an optional GNSS module is available for higher-precision time, location, and data correlation), facilitating data management, in-depth analysis of pollution processes, and traceability—providing a reliable basis for pollution prevention strategies. 

    With high measurement accuracy and excellent stability, the product is widely suitable for environmental monitoring scenarios such as chemical plant boundaries, wastewater treatment plants, and landfills. The CL-2202 is equipped with multiple communication interfaces and supports various communication protocols, offering flexibility for integration into user systems. It can be tailored to meet specific requirements, making it a powerful tool in air pollution control efforts.
