Electrochemical NO2 gas sensor Introduction

Electrochemical NO2 gas sensor is a nitrogen dioxide sensor for accurate detection of nitrogen dioxide (NO2) in the range of 0-20 or 0-2000 PPM. The principle of electrochemical detection is adopted. The gas concentration signal is output to the digital signal required by the customer through the patented circuit. Electrochemical NO2 gas sensor has the characteristics of low power consumption, high accuracy, high sensitivity, short response time, superior accuracy and long-term stability.

Electrochemical nitrogen dioxide sensors and infrared nitrogen dioxide sensors have a wide range of applications. Nitrogen dioxide sensors are suitable for chemical plants, refineries, fertilizer production, public facilities, sewage treatment, pharmaceutical, food and beverage, automotive, mining, military and other industries.

FAQ

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.

WHAT IS THE WORKING PRINCIPLE OF THE NO2 SENSOR?

The NO2 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.
