Product Information

The Aqua Medic Electrode Calibration fluids are ideal to calibrate electrodes and ensure the optimum performance and accurate readings. Aqua Medic have developed a range of calibration fluids, suitable for different electrodes. They should be used routinely to recharge and revitalise your system. A cleaning fluid is also available to keep the electrodes in the best condition.

The accuracy of all electrodes is dependent upon their calibration. To ensure accurate readings, all electrodes need to be calibrated at regular intervals. To ensure that the fluid values used to calibrate the electrodes remain constant, regular replacement of these fluids should occur.

The following calibration fluids are available:

  1. pH: pH 4, pH 7 and pH 9.
  2. Redox potential: 230 mV.
  3. Conductivity: 250 µS, 500 µS, 35 mS, 50 mS.
  4. Refilling fluid for pH and redox electrodes.
  5. Cleaning fluid for all electrodes.

To keep your electrodes safely stored away, use the Aqua Medic Electrode Holder. It will safely store four electrodes until you need them.
