CO tester works well

Hello , my name is chris and I've been a mechanic for 25 or 26 years and I used to own 1 of these until it was stolen . This tool worked great as long as You clean it according to the directions . It is pretty darn accurate and once it is warmed up it is very quick to sense changes in the CO in the exhaust stream . In my opinion if You have a need to test carbon monoxide emissions at the back yard to the semi-professional mechanic level , then this tool is excellent for such especially at the price which is very inexpensive considering .
