Are you a smoker?

You should have read my responses and others in the previous page. Do you have Sensorcon CO detector like mine? If yes, have you tried the same way I did?

I’m not a smoker. I had to blow as hard as I could to the white-tip tube end to get that reading. I figure that it has a vent & filter to reduce the volume rate & moisture.

If I just exhale right on the sensor, it stays zero.

Blow harder to the tube for 5 seconds and tell us what you read.

I think a reading from blowing hard may not be a reading, but an artifact. I see the same thing when calibrating nitrox with my O2 meter. If I pressurize the sensor, the oxygen percentage goes up. If I crack the valve too hard, and seal the lip of the sensor up tight to the DIN valve, I get erroneously high readings.
Maybe one of our engineers can tell us if that's a valid observation, and if so, why that happens.

It sounds like I need to just exhale directly to the sensor. If I do that, the reading will be ZERO.
 
My apologies, Dan. I didn't connect the posts. I think we are on the same page though, in that there should not be CO produced by our bodies in any significant quantities.
