Anyone worked with Industrial-grade Carbon Monoxide Sensor!
-
Hi, I was looking for a reliable carbon monoxide sensor, I tried the MQ7 sensor, but it has a preheat time of 48 hours and a sensitivity range from 20ppm-2000ppm, and my application requires 1ppm to 1000ppm. let me know if anyone working with a similar sensor or use case!
Update: Found that SPEC 3SP_CO_1000 Package 110-102 have 0 to 1,000 ppm sensitivity range and < 100 ppb reseultion, if anyone worked with the sensor let me know. Thanks.
