Description

These are generic ETO 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 ETO gas sensor replacement element.

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

Ethylene oxide detection technologies play a critical role across diverse industrial and medical domains. From manufacturing facilities and medical sterilization to municipal infrastructure and atmospheric research, ETO detectors provide comprehensive gas concentration insights. These advanced sensing systems enable precise measurement, early warning mechanisms, and critical monitoring, supporting safety, public health, and environmental protection 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.
