Humidity Stable Sulfur Dioxide (SO2) Sensors

Electro Optical Components introduces Sulfur Dioxide (SO2) sensors (SO2-20B & – SO2-20BF) that measure Sulfur Dioxide concentrations in the gas phase with no sensitivity loss over time due to humidity. The SO2-20BF has no cross-sensitivity to H2S.  Both can be used as a replacement for the standard 4-series electrochemical Sulfur Dioxide sensors.

Electro Optical Components offers a full line of SemeaTech electrochemical sensors for detecting hazardous materials and gases for work safety and environmental protection.


The SemeaTech electrochemical sensors are distributed in North America by:
