Xylene 4.27 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.
Minimize the sensor’s exposure to these gases as much as possible. If exposure occurs, allow the instrument to draw fresh air and confirm that the readings return to fresh air values. 33 • Measuring Mode, Normal Operation GX-6000 Operator’s Manual...

NOTE: If no button is pressed for 20 seconds, the unit will proceed into whichever mode is displayed. 5 . The warm-up will proceed as described in “Turning On the GX-6000” on page 19. 6 . Once the warm-up sequence has finished, the instrument will be operating in Inert Mode.
Appendix H: 10.0 eV/Benzene PID Sensor Overview This appendix describes the GX-6000’s 10.0 eV/benzene sensor (RKI part number PID-003L). The 10.0 eV/benzene PID sensor detects VOCs in the 0-100.00 ppm range when used in Measuring Mode. It is optimized for benzene detection. The standard calibration for the 10.0 eV/benzene PID sensor is to benzene but it...
3 pins on the back. It is installed in a white housing that has three sockets on the bottom that mate with the GX-6000 instrument. The PID sensor must always be installed in the first smart sensor position which is located in the top left corner of the sensor block.
Tube Holder The tube holder attaches to the GX-6000’s inlet fitting. It has a breakaway feature ensuring that the GX-6000 will not be damaged by hitting the tube holder on something when it is installed. The tube holder should only be used in Benzene Select Mode or when performing a calibration in TUBE CAL.
