About - Nitrogen Dioxide Sensor
Nitrogen dioxide (NO2) is an important industrial gas used in industrial water treatment, pulp and fiber bleaching, oil refining, and leather depilation. Low concentrations (4 ppm) of nitrogen dioxide can cause nasal numbness, and long-term exposure to NO2 concentrations of 40 to 100 mg/m³ can seriously affect health. Therefore, real-time monitoring of nitrogen dioxide concentrations in factories is essential to prevent harm to workers’ health. Renke nitrogen dioxide sensor utilizes electrochemical principles, reacts rapidly, and allows for real-time remote monitoring of nitrogen dioxide concentrations.
RS-NO2-*-*-*-2-T NO2 sensor
The RS-NO2-*-*-*-2-T series is a wall-mounted nitrogen dioxide sensor characterized by its high sensitivity and strong anti-interference capability. Utilizing our company’s unique compensation algorithm and multi-segment gas calibration, it boasts high accuracy, high repeatability, and high stability. Measurement accuracy is within ±5%FS, and repeatability is within ±2%. Measurement ranges of 0-20ppm and 0-2000ppm are available, with other ranges customizable. For applications requiring on-site data viewing, a high-quality OLED display is optional. Power is supplied via a wide 10~30V DC power supply, adaptable to various DC power sources. This wall-mounted nitrogen dioxide sensor is suitable for environments requiring nitrogen dioxide leak monitoring.

RS-NO2-*-2FL-*-T NO2 sensor
The RS-NO2-*-2FL-*-T ducted nitrogen dioxide sensor is designed for measuring nitrogen dioxide gas concentration in enclosed pipelines. It features a waterproof housing and flange mounting. Thanks to our proprietary compensation algorithm and multi-point calibration using standard gases, this sensor offers advantages such as long service life, high accuracy, and good stability. Its anti-interference circuit design allows it to withstand various types of electromagnetic interference, such as interference from field frequency converters. The only difference between the ducted and wall-mounted nitrogen dioxide sensors is their appearance; please refer to the wall-mounted nitrogen dioxide sensor specifications for details. The pricing for the ducted nitrogen dioxide sensor is as follows: 0-20 ppm (without display) $95; 0-20 ppm (with display) $105; 0-2,000 ppm (without display) $105; 0-2,000 ppm (with display) $115.3.
FAQ - Nitrogen Dioxide 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 nitrogen dioxide 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 nitrogen dioxide sensor?
A nitrogen dioxide sensor is an instrument used to detect the concentration of nitrogen dioxide and usually has an alarm function.
What is the working principle of the NO2 sensor?
The nitrogen dioxide sensor uses the electrochemical working principle. It works based on the diffusion of NO2 gas into the sensor and converts the measured NO2 concentration into electrical signal output. Although the concentration of nitrogen dioxide is low, it can still be accurately and reliably measured.
How long do NO2 sensors last?
Under normal circumstances, our NO2 sensor can be used for 5 years.
How to get the manual of the NO2 sensor?
You can leave us a message or email to get the manual.
