Description

These are generic HCl 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 HCL gas sensor replacement element.

Our HCl sensor utilizes an advanced electrolytic mechanism where hydrogen chloride 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 hydrogen chloride levels. The current's magnitude provides a quantitative assessment of HCL presence in various industrial and environmental monitoring applications.

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