To fully comprehend the use of air monitors, the responder must be able to comprehend basic terminology that is generic to all monitors and applies across the board.
More detailed information related to the specific monitors is provided in later sections.
One would think that they mean the same thing, but in reality they are used to describe two different characteristics. Accuracy is the ability of the meter to produce findings close to the actual quantity of gas. An accurate meter when exposed to 100 ppm of a known gas would read 100 ppm. A meter that is not accurate may read 50 ppm instead of the 100 ppm exposure. Precision is used to describe the ability of the monitor to reproduce the same results each time it samples the same atmosphere.
