SO2 / H2S the SOH-A2 measures the two critical Sulfur gases together within one sensor body and using a software algorithm, separates the two gases for clear discrimination. Sulfur gases are toxic with a complex chemistry.SOH-A2 sensor Measuring both SO2 and H2S provides the information for separating the corrosive gases, but with different toxicologies.
SOH-A2 2Sense sensors:
SO2 Spcifications:
Sensitivity:140 to 250 nA/ppm in 10ppm SO2
Response time < 15 t90 (s) from zero to 10ppm SO2
