chemical toxic gas sensors may be degraded at
these levels.
Water should not be allowed to collect on the
sensor as this may impede gas diffusion. Use
with care in wet or humid environments, and
check response after use.
Persistent exposure to high levels of toxic gas
will shorten the life of the sensor. If the gas is
corrosive (e.g. hydrogen sulphide) damage may
occur to metal components.
Sensors may be cross sensitive to other gases.
If unsure, contact Crowcon or your local agent.
Use of high power radio transmitters in close
proximity to the instrument may exceed rated RFI
immunity levels and cause erroneous indications.
If such problems are experienced, remove
antennae to a reasonable separation from the
instrument (e.g. 30cm).
