AREAS OF USE
Exposure to certain chemicals can result in a loss of sensitivity of the
ammable sensor (not applicable to infrared ammable sensor). Where such
environments are known or suspected it is recommended that more frequent
response checks are carried out. The chemical compounds that can cause
loss of sensitivity include Silicones, Lead, Halogens and Sulphur. Do not use
instrument in potentially hazardous atmospheres containing greater than
21% Oxygen. The enclosure material is carbon loaded polypropylene and
must not be exposed to environments which are liable to result in mechanical
or thermal degradation or to damage caused by contact with aggressive
substances. Additional protection may be required in environments where
the instrument enclosure is liable to damage.
