Description

These are generic NO 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 NO gas sensor replacement element.

Our NO sensor employs an advanced electrolytic mechanism where nitric oxide and oxygen interact through precise redox reactions on specialized electrodes. By generating an electrical current directly proportional to the gas concentration, this sophisticated sensor enables accurate measurement of nitric oxide levels. The current's magnitude provides a quantitative assessment of NO presence in various industrial and environmental monitoring applications.

Nitric oxide detection technologies play a critical role across diverse industrial and environmental domains. From manufacturing facilities and urban infrastructure to environmental protection, NO detectors provide comprehensive gas concentration insights. These advanced sensing systems enable precise measurement, early warning mechanisms, and critical monitoring, supporting public health, environmental safety, and technological innovation in multiple application 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.
