Detecting leaks
Over view
Hold the GasCheck G in one hand and draw the
instrument probe along the area to be checked at
approximately 25mm per second. When a leak is
detected retrace the route of the probe at a slower
rate until the leak is located. Once located hold the
instrument over the leak until the measurement
stabilises. The reading can be logged by pressing the
ENTER key.
Some readings may be larger than the instrument can
detect and the measurement units will be replaced by
'99999' on the display, in which case use the UP or
DOWN keys to adjust the instruments sensitivity.
When detecting very small leaks or when detecting
gasses less sensitive, a rate of 10mm per second may
be required.
The outer grey probe cover can be removed to allow better access to restricted areas, if the outer probe is removed
the following points should be noted:-
•
Avoid bending the inner probe as this will affect the GasCheck G's accuracy.
•
Avoid placing the probe in liquid or dirt as the probe can become blocked.
•
Care should also be taken to ensure the brass sensor housing component remains at a constant temperature.
Avoid touching the brass sensor block with fingers.
•
GasCheck G can detect changes in Humidity and Carbon dioxide, therefore avoid breathing on the probe.
•
The thin white tube that covers the inner probe should not be removed, this tube ensures a 1mm gap is
maintained between the probe and the surface being tested.
