REFERENCE JUNCTION KIT

Catalog No. 0059620

CONTENTS

The kit contains: the following for In-Situ’s pH and pH/ORP

sensors:

Three replacement junctions

One 60-mL bottle of reference ﬁlling solution

One dispenser cap

REPLACING THE JUNCTION

Replace the junction when the sensor fails to calibrate with

a reasonable slope and offset, even after replacing the ﬁlling

solution.

1. Unscrew the reference junction and discard.

2. Holding the sensor at an angle, shake out the old ﬁlling solution.

3. Wrap the port end of the sensor in a paper towel to prevent ﬁlling

solution from entering the connector.

4. Using the dispenser cap on the ﬁlling solution bottle, insert the tube

into the bottom of the empty reservoir. Squeeze a steady stream

of new solution into the reservoir until it overﬂows and no bubbles

are observed.

Continue to add solution while withdrawing the tube.

5. Screw in the reference junction and hand-tighten until snug, ﬁrmly

seating the junction. Some ﬁlling solution will overﬂow.

6. Soak the sensor in tap water for at least 15 minutes.

7. Recalibrate the sensor.

Tip: Keep the junction damp at all times to avoid a lengthy

rewetting process.
