These detectors can commonly tell if excess CO2 is present, but if you want a better analysis, try to look for tools that also detect various gas compounds of oxygen and nitrogen.


If the product showed a bunch of numbers, that would not make sense, especially to a beginner. Besides, professionals also do not want the hassle to make additional calculations to derive the answer they need. Hence, check if the device has sufficient logic analyzers.

The screen or the button board should give you a quick idea of the things you can do with the product. So, check for the features you would need specifically before making the final call.
