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.
Apply a few drops of KCl solution to the tip of the probe as shown in the picture below right. The fluid
should completely fill the small moat around the electrodes and form a meniscus on the tip of the sensor.
