Sondes Section 2
2.3 PREPARING THE SONDE FOR USE
To prepare the sonde for calibration and operation, you need to install probes (sensors) into the connectors
on the sonde bulkhead. In addition to probe installation, you need to install a new membrane on the YSI
6572 Free Chlorine Probe. It is highly recommended that you install the free chlorine membrane before
installing the probe onto the bulkhead. The next step is providing power for the sondes, through batteries or
AC, and then connecting a cable. The four steps necessary for getting your sonde ready for use are listed
below.
Step 1 Installing the Free Chlorine Membrane – Section 2.3.1
Step 2 Installing the Probes – Section 2.3.2
Step 3 Supplying Power – Section 2.3.3
Step 4 Connecting a Cable – Section 2.3.4
2.3.1 STEP 1 - INSTALLING THE FREE CHLORINE PROBE MEMBRANE
The 6572 Free Chlorine probe is shipped with a protective cap on the sensor tip which must be removed
before proceeding . Handle the probe with care. It is very important not to drop the probe and/or gouge the
probe tip. See Section 2.10.2, Probe Care and Maintenance, for information on how often the membrane
should be replaced.
Unpack the YSI 6572 Free Chlorine Probe Kit and follow the instructions below
.
FREE CHLORINE SENSOR ELECTROLYTE PREPARATION
Open the 6573 membrane kit which was shipped with your instrument and prepare the electrolyte solution.
Dissolve the KCl in the dropper bottle by filling it to the neck with deionized or distilled water and shaking
until the solids are fully dissolved. After the KCl is dissolved, wait a few minutes until the solution is free
of bubbles.
