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.
