This monitor is only for CO. I don't believe it can detect CO².

Thank you for contacting us. This portable CO gas monitor can freely set the concentration of the alarm value. The sound can be turned on or off The operation is as follows: In the test interface short press the button to turn off the sound (the default is to turn on the sound at boot), at this time the speaker pattern in the upper left corner of the screen disappears. Short press the button again to turn on the sound again."

No. This is not a high range tailpipe analyzer. This is an ambient air analyzer for worker exposure.

Every time it's powered on, it goes through a little 20 second self-calibration routine. You can override it by pressing one of the buttons on the front of the unit.

Depends on the battery and after no use it turns off automatically

I don't know. I sure it depends on how much it is used. I have had mine over a year and working well.

Any exhaust is going to have carbon monoxide, so yes, it could be used as a leak detector.

In the test mode, press and hold the ""MODE"" button to enter the alarm value setting interface: short press the ""°C/°F"" button to switch between numbers, short press the backlight button to edit the value, and then long press the ""MODE"" button to save and exit. The above are the steps of ""Setting the CO threshold level that triggers the alarm"", I hope it will help you!

After the initial countdown it immediately starts measuring CO in parts per million. Mine is very accurate. If yours remains on zero than no CO is detected. If it's doing something weird than maybe it doesn't work. It will not measure CO below 5 ppm eventhough the directs says it will.

I am not the vendor but I think that means the CO level that causes the alarm to sound. It is preset at either 20 or 25 ppm and is adjustable.
