AlphaSense COH-A2 Dual Gas Sensor

The AlphaSense COH-A2 2sense Dual Gas Sensor 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. Note: Once an electrochemical (EC) sensor is purchased from Gaslab.com and the sealed packaging is opened or the sensor module is installed, it is no longer eligible for return due to the limited operational lifespan that begins upon activation. 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
