How do I clean the conductivity cell cup on the portable meters?
  With everyday sampling, the cell cup may build up a residue or film on the cell walls that may cause the readings to become erratic. Use a 1:1 mixture of a common household cleaner such as Lime-A-Way, CLR, Tilex, etc and DI water. Pour into conductivity cell cup and scrub with a q-tip. Be sure to get around all the electrodes and the thermistor probe.

On the portable analog meters, use an acid brush to scrub the cell cup. Let it set for about 10 minutes. Rinse the cell cup thoroughly with tap water, then a final rinse with DI water.
