I got a great heads up by @tbone1004 that a cheaper alternative Carbon Monoxide meter was made by Sensorcon. They have several models that all seem to be good but for $20 more your really better off going with the "Inspector Industrial Pro". I was just about to buy it on Amazon when I decided to check some info on their website and realized that in 2019 they released newer versions! Amazon is still selling the older models from them.
Since their is no price change and the old one is a 2014 version I thought I would warn people. I don't think there are any differences except appearances but the sensors in the new one are certain to be New and the old one may have been on the shelf for a long time. For now you can only get the new one on their website.
