  • Page 35 2.78 • The GX-6000 provides the catalytic combustible sensor with some protection against exposure to high levels of combustible gas which can damage the sensor. It does this by turning off the combustible sensor power temporarily when it determines that an over scale (more than 100 %LEL) concentration of combustible gas is present that may damage the sensor.

    Description Instrument A GX-6000 that contains an 11.7 eV PID sensor is shipped with a black rubber cap plugging the inlet fitting. This rubber cap helps prolong the life of the 11.7 eV PID sensor by preventing ambient moisture from entering the flow system. This rubber cap should be installed back onto the inlet fitting before storing the GX-6000.
