Electrochemical NO2 gas sensor Introduction
Electrochemical NO2 gas sensor is a gas sensor based on electrochemical gas detection technology to detect the concentration of nitrogen dioxide gas in the environment. Electrochemical NO2 gas sensor uses electrochemical principle to detect the concentration of nitrogen dioxide gas in the air. Built-in high-precision nitrogen dioxide sensor has good selectivity and stability. Built-in temperature sensor can be used for temperature compensation. The electrochemical nitrogen dioxide sensor is widely used in the production of portable and stationary nitrogen dioxide gas detection equipment and in various occasions and equipment requiring nitrogen dioxide gas detection.

1. Please connect the electrode foot correctly, the wrong connection position will affect the normal work of the sensor; Sensors should avoid contact with organic solvents, paints, oils and high concentration gases; Do not use adhesive directly on or near the sensor to prevent breakage of the plastic casing.
2. Target gas is recommended for calibration. If cross-sensitive gas is used for calibration, the accuracy of calibration and measurement cannot be guaranteed.
3. Cross sensitivity can fluctuate by up to 30% and may vary with the production lot of the sensor and the life of the sensor.
WHAT IS NO2?
NO2 is nitrogen dioxide, a brown-red, highly reactive gaseous substance. Nitrogen oxide is the general term for nitrogen monoxide, nitrogen dioxide, and other nitrogen oxides, and nitrogen dioxide plays an important role in the formation of ozone. Man-made nitrogen dioxide mainly comes from the release of high-temperature combustion processes, such as exhaust emissions from motor vehicles and power plants. Domestic stoves and gas stoves also produce considerable amounts of nitrogen dioxide.
WHERE TO USE THE NITROGEN DIOXIDE SENSOR?
Nitrogen dioxide tends to accumulate in large quantities in the goaf, mining face, return air tunnel, and other places in underground coal mines. For safety reasons, coal mine enterprises will install NO2 sensor in these places to monitor the nitrogen dioxide gas in real-time. In addition to being used in the coal industry, nitrogen dioxide sensors are also widely used in chemical, meteorological and other industries to monitor the nitrogen dioxide gas content.
WHAT IS A NO2 SENSOR?
A NO2 sensor is an instrument used to detect the concentration of nitrogen dioxide and usually has an alarm function.
