Lamp Cleaning and Electrode Stack Replacement
The TIGER XTS is a sensitive detector. Internal components must be handled
with clean hands and clean tools. The Lamp is fragile. Handle with great care.
Never touch the window and do not drop.
When to Clean or Replace the Lamp
The TIGER XTS MiniPID uses an ultraviolet light source ionising VOC gases as they pass across the
Lamp window. This process may result in a fine layer of contamination on the detector window that
must be removed on a regular basis.
•
In normal use the Lamp should be cleaned after every 100 hours (based on 30 ppm for 100
hours). If the Tiger XTS is used in heavily gas contaminated environments, the Lamp should
be cleaned more often.
•
Please note that some esters, amines and halogenated compounds may accelerate window
fouling; in these cases cleaning may be required after every 20 hours of use.
•
Cleaning frequency will also depend upon alarm levels set and prevailing environmental
conditions.
•
Damaged Lamps must be replaced immediately. Do not use a Tiger XTS with a damaged
Lamp.
