Description

These are generic H2 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 H2 gas sensor replacement element.

Our H2 electrolytic sensor operates by facilitating a reaction between hydrogen and oxygen at its working and counter electrodes. This electrochemical process generates an electric current directly proportional to the hydrogen concentration. By precisely measuring the resulting current, the sensor can accurately determine the hydrogen levels, providing a reliable method for hydrogen detection and quantification.

Our versatile H2 sensor finds critical applications across multiple domains, including industrial site monitoring, on-board hydrogen detection, municipal hydrogen management, and environmental protection. This advanced sensor technology enables precise hydrogen detection in diverse settings, ranging from industrial facilities to smart urban infrastructure. Its comprehensive capabilities support safety protocols, environmental monitoring, and technological advancements in hydrogen-related applications.

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.
