11.6.3.3 Cleaning the PMT Lens & PMT filter
NOTE:
The sample chamber should only be opened or cleaned on instructions from the Teledyne Instruments
customer service department.
Be careful not to leave thumbprints on the interior of the sample chamber. The various oils that make up
fingerprints fluoresce brightly under UV light and will significantly affect the accuracy of the analyzer’s
SO2 measurement.
To clean the PMT Lens and filter:
1. Remove the sensor module as described in Section 11.6.3.1
