ENGLISH
Severe contamination and high concentration of moisture reduce the lifetime of the sensors
significantly. Poisoning of the sensors occurs if they are exposed to silicone vapour and sol-
vents, (painting work), freons (old cooling systems) or vapour from leaded petrol and polyester
resins while they are switched on.
In order to prevent damage to the sensors it is recommended that the gas detector is switched
off under the conditions named above or even to remove the sensors from the ship tempo-
rarily.
N B The presence of petrol vapour and CO will then no longer be detected Do not forget
to consider safety!
The sensor ages while being used to measure the concentration, and this is faster during
continuous than during intermittent use. After about 2 years of continuous use the sensor will
have aged, see '4 Ageing of the sensor' .
