6. OPERATION
6.1. Environmental conditions
The lifetime of t he electrochemical cartridges for toxic gas detector depends on the
operating environment related to temperature, humidity and high exposures.
One will take care to avoid long exposures to a hot and dry atmosphere (T°> 30°C and
RH<10%), and gas exposures 4 times higher to the scale.
The lifetime of the cartridges for semi-conductor toxic gas detector depends on the
operating environment related to certain compounds.
One will take care to avoid exposures to some vapored products as silicone. Moreover, an
exposure in area with a low rate of hygrometry for several hours can temporarily damage the
sensitivity. In order to retain stability of the factory span calibration, we recommand to leave
in place the protection cap with a desiccant packet on the front of the cartridge during
storage, shipping or any periods without power lasting more than 1 hour.
Don’t forget to remove the protection cap after power ON and before inserting
the eventual splash-guard.
Store the protection caps with the desiccant packet in a sealed container (zip-
lock bag). Dry the bag before using it again
In general, a dusty and humid atmosphere must be avoided. Indeed, a clogging of the gas
barriers is then possible, slowing down or stopping the detection process.
