COH-A2 Alphasense 5,000ppm Carbon Monoxide and Hydrogen Sulfide Gas Sensor

The COH-A2 Alphasense Dual Gas Sensor (formerly known as the AP-0011) detects both carbon monoxide and hydrogen sulfide in a single sensor. It is designed for OEM manufactures who need to measure both gases as well as a replacement sensor for several models of personal gas safety monitors. For Sensor Tube Caps, please look under the "Accessories" Tab Features Low Cross-Sensitivity No external power required Proven and tested design This 20mm diameter, 4-pin sensor is the industry standard size for portable gas detectors. The 2sense does not compromise performance or long term stability over the standard two-sensor solution when measuring both H2S and CO. Specifications - Carbon Monoxide Sensitivity: nA/ppm in 400ppm CO 50 to 100 Response time: tgo (s) from zero to 400ppm CO < 35 Zero current: ppm equivalent in zero air -3 to +3.5 Resolution: rms noise (ppm equivalent) < 0.5 Range: ppm CO limit of performance warranty 1,000 Linearity: ppm error at full scale, linear at zero an
