Button Type MEv-GH01 Long-Life Hydrogen Sensor Module Hydrogen Leak Detection Probe Gas Sensor

Button Type MEv-GH01 Long-Life Hydrogen Sensor Module Hydrogen Leak Detection Probe Gas Sensor

Profile:

The MEv - GH01 is a fuel cell - type sensor that operates based on the electrochemical principle. It leverages the electrochemical oxidation process of hydrogen on the working electrode inside the electrolytic cell. The electric current generated by the electrochemical reaction of hydrogen is proportional to its concentration and complies with Faraday's Law. Therefore, the concentration of hydrogen can be accurately determined by measuring the current value.

Core Features:

1. Low Power Consumption: It features a low - power design, which makes it applicable to various battery - powered devices and scenarios with strict power consumption constraints, such as vehicle - mounted equipment.
2. High Detection Performance: It boasts high precision and high sensitivity, with a resolution of 1 ppm. Additionally, it has a wide linear output range, enabling accurate and reliable measurement of hydrogen concentration within the effective range.
3. Stable and Durable: It has excellent repeatability, with the repeatability error being less than 5% of the output value. The anticipated service life can reach 10 years, ensuring long - term stable operation in appropriate working environments.
4. Good Anti - Interference Ability: Although it may respond to some non - target gases, its overall anti - interference performance is commendable. For instance, when exposed to 15 ppm hydrogen sulfide, its response is 4 ppm; when encountering 200 ppm carbon monoxide, the response is 30 ppm, which has little impact on the accurate detection of hydrogen.
5. Broad Environmental Adaptability: It can work stably in diverse environmental conditions. It adapts to common temperature ranges of -10℃ - 50℃ and can occasionally operate in the harsh temperature environment of -40℃ - 70℃. Meanwhile, it is suitable for the humidity range of 15% - 90% RH and can run normally under the pressure condition of standard atmospheric pressure ± 10%.

Applications:

This sensor is extensively used for hydrogen concentration detection in commercial fields, energy storage power stations, vehicle - mounted systems, small generators, and industrial gas safety control. It can also be applied in process engineering testing and hydrogen leakage detection scenarios, providing reliable support for safety monitoring in relevant fields.
