Description

These are generic PH3 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 PH3 gas sensor replacement element.

Our PH3 sensor employs an advanced electrolytic mechanism where phosphine 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 phosphine levels. The current's magnitude provides a quantitative assessment of PH3 presence in various industrial and environmental monitoring applications.

Our phosphine detection technologies play a critical role across diverse industrial and environmental monitoring domains. From manufacturing facilities and animal husbandry to smart municipal infrastructure and environmental protection, PH3 detectors provide comprehensive gas concentration insights. These advanced sensing systems enable precise measurement, early warning mechanisms, and critical monitoring, supporting safety, environmental health, and regulatory compliance 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.
