The model ACM3 carbon monoxide accessory head enables most digital
multimeters to measure low levels of carbon monoxide in parts per
million (PPM). It is intended to measure levels of CO in still
ambient air. In many cases, it can help pinpoint sources of CO. It
uses a catalytic chemical sensor that consumes no chemicals. Life
if primary determined by the type of exposure.
The most practical application is to determine if the indoor CO
levels are higher than outdoor levels and to determine the source.
This instrument detects changes in CO levels very quickly.
"Walk around" Test
The ACM3 is fast enough to respond almost instantaneously to
changes in CO levels in the air. If you see a difference in CO
levels from outside to inside, you need to find the source of the
CO. Walk around and watch the display. By constantly going towards
the area of highest concentration, you can determine the source of
the CO. It may be that someone just drove their car into the garage
and opened the kitchen door and you don't have to take any action.
Or it could be that the furnace is starved for air and that CO is
entering the house. You've got to fix that!
