Product Description

●Intrinsically safe circuit design, explosion-proof certification, secondary lightning protection, anti-static, lightning protection and anti-static capabilities exceed national standards, and can withstand high-intensity pulse surge current impacts. High reliability and stability.

●Standard bus RS485 and 4~20mA standard signals are output simultaneously, 1 set of relay switching output, optional frequency output 200-1000Hz, 1~5V output, wireless transmission (10-50 kilometers or unlimited distance). It can be wired or wireless remote real-time monitoring, and the data can be uploaded to a mobile phone or transmitted to the Environmental Protection Bureau, other monitoring centers, monitoring equipment, and monitoring computers through LAN or the Internet, and the on-site concentration can be monitored in real time through free host computer software or gas alarm controllers.

●It is compatible with various secondary meters, data acquisition modules, PLC, and DCS systems. It can directly drive solenoid valves, fans, alarms and other equipment, and can also drive high-power equipment by driving intermediate relays.

●The standard infrared remote control enables operation without opening the cover in dangerous situations.

●2.5-inch high-definition color screen (TF) displays real-time concentration, temperature, humidity.

●Automatically tracks zero point to prevent drift, temperature compensation, multi-level calibration, and can comply with national standards and local and provincial metrology bureau standards in various regions.

This is an explosion-proof fixed carbon dioxide (CO2) gas detector, specifically designed for industrial environments to perform 24/7 continuous online monitoring of CO2 concentration.

Core Application Scenarios​

Chemical & Petrochemical Industry​

Used in processes such as coal chemical, synthetic ammonia production, and carbonate ester manufacturing. Monitors CO2 leaks at reaction vessels, tank farms, and pipeline connections to prevent risks of hypoxia, suffocation, or explosions caused by gas accumulation.

Typical scenarios: petroleum refineries, fertilizer plants, fine chemical workshops.

Energy & Power Industry​

Used in coal/gas-fired power plants for boilers, flue ducts, and post-combustion treatment processes to monitor CO2 emissions, optimize combustion efficiency, and meet environmental standards.

Applied in confined spaces such as utility tunnels and gas pipeline maintenance to prevent accidents due to CO2 buildup.

Food, Beverage & Fermentation Industry​

In beer, carbonated beverage, and bioprocessing workshops, where CO2 is widely used as a raw material or by-product. The detector monitors gas concentrations in production and fermentation tank areas to ensure personnel safety.

Metallurgy & Manufacturing​

In high-temperature processes like blast furnaces and converters in steel plants, where CO2 is a major emission. The detector supports process control and safety protection.

In welding workshops and metal processing facilities, CO2 shielded welding releases significant gas, requiring real-time monitoring to ensure a safe working environment.

Special Confined Space Operations​

In ventilated-restricted locations such as mines, tunnel construction, underground parking garages, and wastewater treatment plants, to prevent hazardous hypoxia caused by excessive CO2 concentration.
