This PCMM05 uses the latest electrochemical sensors and can react to ambient changes in carbon monoxide quickly. It's an ideal tool for measuring CO levels in industrial environments, commercial buildings, or residential dwellings. Measures CO levels from 0 to 1000 PPM. Max hold and data hold functions. A built-in alarm sounds when CO concentration hits 200 PPM or higher. Auto power off keeps the included 9V battery charged as long as possible.

We had two Carbon Monoxide alarms go off last week in our home and I bought this to take spot readings. Solidly built and easy to operate with protective red casing and a pocket pouch. Display is easy to read and audible alert to CO level is good. I am very pleased with the price and quality of this product. (Posted on 6/8/2016)
