CO Analizer accuracy

Mitch_6

of my c.o. Analyzer. I have a TSI 6130 analizer and am questioning it's accuracy. I am looking for some simple way of comparing to a known c.o. level.

Are kits like UEI's SGACALKIT usable for spot checks say once a week, month or every other month.

Any Ideas or opinions on verifying within reason our readings.

Analyzer Accuracy

I have been testing analyzers for over 20 years with certified test gas, most makes and models. The question comes up all the time about why do they read different in the flue gases. Its all about the CO sensor. Manufacturers such as TSI and Testo use more accurate sensors with filters that remove NO & SO which cause CO sensors to drift high. Bacharachs tend to read higher than any other meter when it comes to CO. If I had a choice this is the better direction to error. Sometimes it is just the location in the flue that makes the difference as flues can have turbulence that can cause CO to vary up to 50%. Just find the highest reading in the flue that you can and trust what you see.
