CO / H2S the COH-A2 gas sensor measures H2S Hydrogen Sulfide,CO Carbon Monoxide. Alphasense new 2sense H2S+CO gas sensor allows designers to reduce significantly their gas detector size and cost. The 2sense CO/H2S Sensor uses a patented approach to dual gas sensor design and utilises our also patented low Hydrogen sensitivity CO electrode.
COH-A2 2Sense sensors:
CO Spcifications:
Sensitivity:50 to 100 nA/ppm in 400ppm CO
Response time < 35 t90 (s) from zero to 400ppm CO
Resolution< 0.5rms noise (ppm equivalent)
Range:1000 ppm CO limit of performance warranty
H2S specifications:
Resolution < 0.1rms noise (ppm equivalent)
Range: 100ppm H2 S limit of performance warranty
