NO2 gas sensor-Nitrogen dioxide gas detector
Featured Product
NO2 gas sensor
NO2 gas sensor is used to detect the concentration of nitrogen dioxide gas in the air of the gas sensor, using the principle of electrochemical detection, through the patent circuit will be gas concentration signal output to the digital signal customers need. The NO2 gas sensor has the characteristics of low power consumption, high precision, high sensitivity, short response time, superior accuracy and long-term stability, and has the same wide application range as the infrared nitrogen dioxide sensor.
Portable Nitrogen dioxide gas detector
Portable nitrogen dioxide gas detector is a kind of gas sensor that can detect nitrogen dioxide gas concentration anytime and anywhere, and can alarm by sound and light. Portable appearance of no2 gas detector humanized design, accord with mechanics principle, on the premise of guarantee the sensitivity and accuracy, strengthen human body comfort, with the limit alarm functions, when nitrogen dioxide gas more than the set value of gas, nitrogen dioxide sensor will open the light alarm, high decibel buzzer alarm, meter standard red, timely warning, high safety.
NO2 Gas Detector
The NO2 gas detector can continuously detect nitrogen dioxide concentrations online in some harsh environments. NO2 gas detector can not only control the concentration of nitrogen dioxide in special occasions, but also have an early warning effect on nitrogen dioxide leakage in dangerous sites. The fixed nitrogen dioxide gas sensor is widely used in petroleum, chemical, metallurgy, fire, coal mine, electric power, shipbuilding, environmental protection and other industries. It has the advantages of signal stability, high precision and good repeatability.
NDIR Nitrogen dioxide gas sensor
NDIR Nitrogen dioxide gas sensor is an infrared gas sensor based on infrared absorption detection (NDIR) principle. Infrared NO2 gas sensor adopts imported light source, special structure optical cavity and double channel detector to realize space double optical path reference compensation. Infrared nitrogen dioxide sensor has the advantages of high sensitivity, no oxygen dependence, long life, low power consumption and so on. NDIR Nitrogen dioxide sensor Built-in temperature sensor for temperature compensation. Small size, plug – out installation mode, convenient for customers to various applications.
Frequently Asked Questions​
What is NO2 gas?
At room temperature (0~21.5℃), NO2 is a poisonous and irritating gas. Dissolve in concentrated nitric acid and produce fuming nitric acid. It can be superimposed to form nitrous oxide. Reacts with water to form nitric acid and nitric oxide. Reacts with base to form nitrate. Can react violently with many organic compounds.
What kinds of Nitrogen dioxide detector are there?
Nitrogen dioxide gas detector according to different occasions, is also divided into different types, mainly divided into portable hydrogen sulfide detector and online Nitrogen dioxide detection alarm.
What is an Nitrogen dioxide sensor?
Nitrogen dioxide sensor is a gas sensor developed to detect the concentration of nitrogen dioxide in the air. The measurement results are accurate and effectively protect the safety of staff.
How should the NO2 gas detector be calibrated?
First, place the NO2 detector in an ozone-free environment, check whether the measured value is zero, if it is not zero, you need to manually adjust the zero. Secondly, an NO2 generator is used to create an ozone environment, and the measured value of the NO2 detector is compared with the measured value of the higher precision NO2 detection equipment of the same range.
