WARNING!
The Wöhler GS 300 may never be used in an environment where there is the risk of
explosion. If the environment is suspected to conglomerate potentially explosive gases,
in no case you must use the Wöhler GS 300. Batteries may not be taken from the
device and/or be changed in such an environment.
ATTENTION!
Always store the device in a closed case at clean air. The sensor will be damaged , if it
is exposed to extreme conditions for a long time, e.g. a high degree of relative humidity,
extreme temperatures or pollution.
ATTENTION!
Avoid exposure to silicone adhesives, e.g. in cleaning tools. Silicone vapors will cause
damage to the sensor.
ATTENTION!
High-density exposure to corrosive materials such as H
cause corrosion or breakage of the lead wires or heater material.
ATTENTION!
Protect the sensor against salt water vapor and water. Sensor drift may occur when the
sensor is contaminated by alkaline metals, especially salt water spray.
Light condensation under indoor usage should not be a problem for sensor. However, if
water condenses on the sensor's surface for a while, the sensor characteristics may still
drift.
ATTENTION!
If water freezes on the sensing surface, the sensor would crack and alter characteris-
tics.
ATTENTION!
Sensor performance may be also affected if exposed to a high density gas for a long
time, regardless of the powering condition.
NOTE!
This meter cannot work well in zero or low oxygen atmosphere. This meter requires to
operate under around 21% ambient oxygen environment in order to function properly.
