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 can be factory setup for and calibrated to
other gases. Regardless of the calibration gas, the 10.0 eV/benzene sensor will still detect
and respond to a variety of volatile organic compounds (VOCs) while used in Measuring
Mode. Even though the 10.0 eV/benzene sensor can be used for general VOC detection, if
your application is for general VOC detection and is not related to monitoring for benzene
specifically, RKI Instruments, Inc. recommends that the low range or high range 10.6 eV
PID sensor be used instead.
The 10.0 eV/benzene PID sensor detects VOCs in the 0-50.00 ppm range when used in
Benzene Select Mode. The filter tube that needs to be used in Benzene Select Mode allows
benzene to pass through but scrubs out all other VOCs except for nitrobenzene,
cyclohexane, n-octane, and n-pentane. Common applications for the 10.0 eV/benzene PID
sensor include process monitoring where only benzene is present or petroleum industry
monitoring where other VOCs may be present.
See the table below for 10.0 eV/benzene sensor specifications.

Sensor Description
The PID sensor is a cylindrical sensor with a diffusion opening on the front and 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.
