CARBON MONOXIDE ELEMENT #MI
-
4002R
DESCRIPTION
This detector consists of a ‘Visual” indicator (#MI
-4000), into which a small (15 mm
diameter) replaceable disc is inserted. The ‘Visual’ indicator has a clear sight lens through
which the disc may be seen. The disc changes color in the presence of low concentrations
of carbon monoxide within 5 to 10 minutes of exposure and therefore acts as a clear visible
warning before the proportion of gas reaches an unacceptable level. If higher and more
dangerous concentrations or carbon monoxide are present, the disc changes color within a
few seconds.
USAGE
The detection disc is specially treated to prolong its life. A color change from tan to dark
grey will occur in the presence of carbon monoxide. The rate if change of color is directly
related to the concentration of carbon monoxide present. The detector will change color in
five to ten minutes at 50
–
100 ppm of carbon monoxide, but will change color within a few
seconds if the level reaches 500-1,000 ppm (0.05%-0.1%), at which concentration it can
be lethal.
BENEFIT
The detector is a quick, inexpensive and simple means of showing the presence of carbon
monoxide in the sample air. There is no need for troublesome sampling equipment or
expensive analytical equipment. The change in color is easy to spot and the results can
be interpreted by non- specialist staff.
