AREAS OF USE
Exposure to certain chemicals can result in a loss of sensitivity of the flammable
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 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.
STORAGE, HANDLING AND TRANSIT
The batteries in the rechargeable pack contain considerable energy and care
should be taken in their handling and disposal. Battery packs should be removed
if the instrument is stored for longer than 3 months. The instrument is designed
to handle harsh environments. The sensing elements are sealed to IP54 and the
rest of the instrument to IP64. If not subject to misuse or malicious damage, the
instrument will provide many years of reliable service. The instrument contains
electrochemical sensors with a life of 2 years. Under conditions of prolonged storage
the sensors should be removed. The sensor contains potentially corrosive liquid
and care should be taken when handling or disposing of the sensor, particularly
when a leak is suspected.
