We have a mains powered CO tester in the same room as our log burner.

However I am wondering if there is a sensitive portable CO tester which is
good.

9E1000ppm/dp/B08CSLLXVC/
is an example after a quick search.

The main question is if these detectors are more accurate/sensitive than
the ones designed for permanent installation.

Any recommendations based on experience most welcome.


We have a FireAngel with a digital display which happily sits there
showing anything 20-odd ppm when others indicate nothing because they
are designed to start /sounding/ warnings only at levels above 50.
Model is no longer available but I think it likely current digital ones
from FireAngel and from other makers (eg Kidde) with digital displays
would do likewise.
