ME3-HF Electrochemical Hydrogen Fluoride Gas Sensor159

For Portable and Fixed HF Gas Detector

ME3-HF electrochemical sensor detect gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current.

MQ-2 Semiconductor Smoke Sensor

Household flammable Gas Sensor

Sensitive material of MQ-2 gas sensor is SnO2, which with lower conductivity in clean air. When the target flammable gas exist, the sensor’s conductivity gets higher along with the gas concentration rising.Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. MQ-2 gas sensor has high sensitivity to propane and smoke, also can detect the natural gas and other flammable steam well. It is with low cost and suitable for different applications of detecting kinds of flammable gases.

MQ-3B Semiconductor Alcohol Sensor

For alcohol gas alarm and portable alcohol detector

Sensitive material of MQ-3B gas sensor is SnO2, which with lower conductivity in clean air. When the target alcohol gas exist, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. MQ-3B gas sensor has high sensitivity to alcohol gas and can resistant to the interference of gasoline, smoke and vapour. It is with low cost and suitable for various applications of detecting alcohol at different concentration.

ZE08-H2 Catalytic type Hydrogen Gas Sensor Module

For industry Hydrogen gas leak alarm

This ZC08-H2 Module adopts catalytic gas sensor and has basic function of home use gas leakage alarm with digital display: supplying digital UART signal and supporting alarm point resetting. It is usually used for hydrogen gas leakage detector.

ME3-O3 Electrochemical Ozone Sensor

For commercial and environmental usage to detect O3

Industrial process CO2 monitor and control

Industrial process CO2 monitor and control

+

Carbon dioxide (CO2) is a colorless and odorless gas at room temperature. It is widely found in industry, agriculture, animal husbandry, residential environments and public places. However, high level CO2 can cause human body poisoning.Therefore, carbon dioxide monitoring is used in production processes that are prone to occupational exposure to various hazards that produce carbon dioxide, such as beer and beverage brewing, CO2 emission control in industrial sites, CO2 control in the transportation of fruits and vegetables, and cold storage environments.

HVAC
