Description

These are generic NO2 sensors used as the pin-to-pin replacement of the standard 4-series electrochemical sensors. It is used throughout many gas detector brands and is an excellent NO2 gas sensor replacement element.

Our NO2 nitrogen dioxide sensor utilizes an advanced electrolytic mechanism where nitrogen dioxide and oxygen undergo redox reactions on specialized electrodes. This process generates an electrical current directly proportional to the nitrogen dioxide concentration. By precisely measuring the test current's magnitude, the sensor can accurately determine and quantify the presence of nitrogen dioxide in various environmental monitoring applications.

Our NO2 detection technologies play a critical role in diverse industrial and environmental monitoring applications. From industrial sites and mining operations to smart city infrastructure and environmental protection initiatives, NO2 detectors provide essential insights into gas concentration levels. These advanced sensing systems enable comprehensive monitoring, early warning mechanisms, and precise measurement of nitrogen dioxide, supporting safety, environmental health, and regulatory compliance across multiple sectors.

Instructions

• Once replaced and installed in your gas detector or analyzer, please let it sit for 24 hours so the sensor can stabilize to your environment. This step is very important.
• Then undertake the appropriate zero and calibration for your specific gas detector. See your gas detector manufacturer's specific instructions.
• Once calibrated, your gas analyzer will be ready for use.
