Description
These are generic SO2 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 SO2 gas sensor replacement element.
Our SO2 sensor employs an advanced electrolytic mechanism where sulfur dioxide and oxygen engage in precise oxidation-reduction reactions across specialized electrodes. By generating an electrical current directly proportional to the gas concentration, this sophisticated sensor enables accurate measurement of sulfur dioxide levels. The current's magnitude provides a quantitative assessment of SO2 presence in various environmental and industrial monitoring applications.
Our SO2 detection technologies serve as critical monitoring tools across diverse industrial and environmental sectors. From industrial sites and livestock facilities to smart city infrastructure and atmospheric research, SO2 detectors provide comprehensive gas concentration insights. These advanced sensing systems enable precise measurement, early warning mechanisms, and comprehensive monitoring, supporting environmental protection, public health, and regulatory compliance in multiple critical application domains.
Instructions
- Once replaced and installed in your gas detector or analyzer, please let it sit for聽24 hours聽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.
