Description

These are generic NH3 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 NH3 gas sensor replacement element.

Our NH3 sensor employs an electrolytic mechanism where ammonia gas and oxygen undergo oxidation-reduction reactions on working and counter electrodes. As these reactions occur, electrical charges are generated, producing a current directly proportional to the ammonia concentration. By precisely measuring this current, the sensor can accurately determine and quantify the presence of ammonia in a given environment.

Our Ammonia detection technology plays a crucial role across diverse sectors, addressing critical safety and environmental monitoring needs. From industrial sites and animal husbandry to municipal infrastructure and atmospheric research, these advanced sensing systems provide comprehensive monitoring capabilities. By leveraging sophisticated sensors and real-time analytics, ammonia detection technologies enable early warning mechanisms, environmental protection, workplace safety, and precise measurement of gas concentrations in complex and dynamic environments.

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.
