• For long-term storage rinse the electrodes with water. Shake off the excess
water and replace the storage cap to prevent evaporation of the reference
electrolyte.
• For chloride sensors (HI 7609829-11), if the sensor pellet appears tarnished,
use a polishing strip to remove the oxidized surface. Cut off approximately a 1
inch piece of the strip. Wet the frosted side with water and place against dam-
aged surface. Place your thumb against the shiny backing and slowly rotate
back and forth while applying gentle pressure.If dark deposits appear on the
frosted surface, move the paper slightly. Continue polishing until you are satis-
fied with the surface. Rinse sensor with water.
