Appendix I: 11.7 eV PID Sensor
Overview
This appendix describes the GX-6000’s 11.7 eV PID sensor (RKI part number PID-004).
The 11.7 eV PID sensor detects VOCs in the 0-1000 ppm range. The standard calibration
for the 11.7 eV PID sensor is to isobutylene but it can be factory setup for and calibrated to
other gases. Regardless of the calibration gas, the 11.7 eV PID sensor will still detect and
respond to a variety of volatile organic compounds (VOCs) while used in Measuring
Mode.
The 11.7 eV PID sensor is capable of detecting VOCs that the 10.6 eV low range and high
range PID sensors are not, such as:
•
acrylonitrile
•
carbon tetrachloride
•
chloroform
•
methanol
•
refrigerants (R-32A, R-143)
See the table below for 11.7 eV PID sensor specifications.

11.7 eV PID Lamp Warranty
The PID-004 11.7 eV PID sensor’s lamp (RKI P/N 51-1504) is susceptible to humidity
and its service life is not as long as lamps in other PID sensors sold by RKI Instruments,
Inc. For this reason, the PID-004 11.7 eV sensor’s lamp is warranted for 2 months from
the date of shipment.
