CAUTION: The GMI PS200 instrument can be supplied
with a flammable gas sensor. This sensor is
designed for use in concentrations of gas not
exceeding the Lower Explosive Limit (LEL).
Exposing the sensor to high concentrations of
flammable gas above the LEL can cause
damage to the sensor and inhibit its proper
operation. The GMI PS200 has an inbuilt safety
alarm feature to prevent this. Refer to ALARMS
section of this handbook for details.
