With multiple detection range options, this high-performance sensor is ideal for a variety of applications, including chemical processing, power plants, and environmental monitoring.
Anti-magnetic interference
- The fixed nitrogen oxides (NOX) can resist the strong magnetic interference of 15V/meter.
- In areas with dense magnetic products or dense electronic products, such as tunnels, mines, confined spaces, etc., the data is guaranteed to be stable and reliable.
Using high-precision sensors
- The fixed nitrogen oxides gas detector is equipped with an infrared remote control as standard, which can realize the functions of alarm point setting, zero point calibration, and address modification without opening the cover.
- Compatible with various control alarms, PLC, DCS and other control systems to realize remote monitoring.
Variety of installation methods
- Wall mounted type, installed on the wall directly, real time monitoring.
- Piping type, installed on the pipeline, monitoring the gas concentration inside.
- Flow type, connected with external sampling pump and tube, measure the gas concentration in enclosed space.
Applications
The fixed nitrogen oxide (NOx) Gas Detectors are widely used in industries such as manufacturing, power plants, and automotive to monitor and control NOx emissions. These detectors help ensure compliance with environmental regulations by providing real-time data on air quality and pollutant levels, thereby reducing the risk of harmful emissions..

SISCO Gas Detector Catalogue.pdfQ1: What is a fixed gas detector?
A1: The fixed gas detector is composed of sensors and transmitters, and is installed at the detection site. The secondary instrument consisting of circuit, power supply and display and alarm device is installed in a safe place, which is convenient for staff to monitor. In industrial installations and production processes, fixed gas detectors are generally used, because fixed gas detectors can be installed at specific detection points to detect specific gas leaks.
Q2: What does a gas detector detect?
A2: Combustible gases: Natural gas (methane), liquefied gas, coal gas (hydrogen), acetylene, pentane, alkynes, acetone, toluene, alcohols, hydrocarbons, light oil, etc.
Toxic gases: Carbon monoxide, hydrogen sulfide, ammonia, chlorine, oxygen, phosphine, sulfur dioxide, hydrogen chloride, chlorine dioxide and other toxic and harmful gases.
Q3: Difference between fixed gas detector and portable gas detector
A3: The biggest advantage of fixed gas detectors is 24-hour uninterrupted measurement. As long as the power is turned on, the fixed gas detector is in normal detection work. Portable gas detectors are usually used in confined spaces and confined spaces, but the gas environment in these spaces is usually very complex, and there will be situations such as lack of oxygen and high concentrations of harmful gases.
Tips:Â How does a oixed nitrogen oxides gas detector work?
A Fixed Nitrogen Oxides (NOx) Gas Detector works by using sensors to measure the concentration of nitrogen oxides (NO and NO2) in the air. These detectors typically employ electrochemical, chemiluminescence, or semiconductor sensors to detect the gases.
- Electrochemical sensors: These sensors react with NOx gases, generating a current proportional to the concentration of the gas. This current is then measured and converted into a gas concentration reading.
- Chemiluminescence sensors: This method relies on a chemical reaction between nitrogen oxides and ozone, producing light. The intensity of the light is proportional to the concentration of NOx, and it is measured to provide the gas levels.
