PROBE MAINTENANCE & CLEANING

For a top performance probe, it is recommended to replace the membrane
every 2 months and the electrolyte once a month.
Proceed as follows:

• Unscrew the membrane by turning it counterclockwise.

• Rinse the supplied spare membrane (HI 764

09A/P) with some

electrolyte solution while shaking it gently. Refill with clean

electrolyte.

• Gently tap the membrane over a surface to ensure that no air

bubbles remain trapped.

• With the sensor facing down screw the cap clockwise to the end

of the threads. Some electrolyte will overflow.

If any deposit scales the sensors, gently brush the sensor surface with the
supplied scouring pad, while paying attention to not damage the plastic
body.
