6.6 Maintenance of Sampler O-ring
The sampler nozzle O-ring wears over time. Perform weekly cleaning, monthly inspection, and an-
nual replacement.
WARNING:
When inspecting and replacing O-rings, always wear gloves, a lab coat, and safety goggles.
If you accidentally touch a contaminant, immediately rinse the contaminated area thoroughly un-
der running water, and then disinfect the area.
Seek medical assistance if necessary.
IMPORTANT:
If you do not inspect and replace the sampler O-ring, the sample application volume will be inac-
curate, which may negatively affect the measurement values.

1. Prepare a dry / damp gauze or cloth (eye-
glass wipes, lint-free cloth, etc.).
