Locate the 6035 Reconditioning Kit which was supplied with your 6572 Free Chlorine Probe. Use one of
circular sanding disks the 6035 Reconditioning Kit to sand the face of the 6572 Probe according to the
following instructions.
•
Hold the probe in a vertical position, place a sanding disk under your thumb, and stroke the probe
face in a direction parallel to the platinum electrode (located between
the two silver electrodes). The motion is similar to that used in
striking a match. Usually 10-15 strokes of the sanding disk are
sufficient to remove black deposits on the silver electrodes.
However, in extreme cases, more sanding may be required to
regenerate the original silver surface.
•
Rinse the probe tip well with purified water to remove dust from
sanding.
CAUTION: You must sand your free chlorine sensor as described
above prior to installing a membrane to insure the surface tension
for probe surface/membrane interface.
Locate the YSI 6574 O-ring Installation Kit which was shipped with your sonde. Note that the kit contains
two items – a circular plate with a threaded hole and a cylindrical tool with a screwdriver-style handle as
shown in the picture below.
Thread the nut on the end of the 6572 probe into the base plate as shown in the picture below.
Place an o-ring from the 6573 membrane kit in the groove at the bottom of the tool as shown in the picture
below left.
