PROBE
The instrument is provided with a probe containing both a
cotton and a hydrophobic filter.
The probe ends can be changed to provide a short probe
with an open end, or a long probe with a closed end.
The filters in the probe should be changed by the operator
as required.
The cotton filter should be changed on a regular basis,
say once per week depending on use, when dirty,
contaminated by water, etc.
The hydrophobic filter should only be replaced when
contaminated with dirt or water and cannot be cleared.
