Electrochemical Integrated Gas Sensor Module ZCE04B

Summary:

The 4-in-1 detection module ZCE04B is mainly aimed at various places where ambient gas detection is required. The product contains four gas sensors (expandable for CO, H₂S, O₂ and CH₄ gases) and a signal processing circuit board. The module has good selectivity and stability. The module can output the current concentration values of the four gases in real time through the digital serial port output. It can be used in handheld devices or fixed devices to detect the current concentration of ambient gas. This module is a general-purpose miniaturized product that closely combines mature sensor detection technology and sophisticated circuit design.

Feature:

* High integration, small size,
* Good stability and fast response
* Real-time serial port output concentration, easy to use

Coal Mining Industry Poison Gas Monitoring

Flammable gas is mainly detected by catalytic sensor, mainly measuring 100% LEL, and also using thermal conductivity components to measure 100% VOL. High-end gas detection products in the petrochemical industry are gradually using infrared gas sensors, which can measure 100% LEL and 100% VOL. At the same time, laser beam technology is also gradually being used in the petrochemical industry.

Industrial Exhaust Monitoring

Industrial waste gas refers to the general term for various pollutant-containing gases discharged into the air generated during the fuel combustion and production process in the factory area of the enterprise. These gases enter the human body through the respiratory tract through different routes, some directly cause harm, and some have an accumulation effect, which will seriously endanger human health.
