Aqua Medic Test Fluid 230mV Redox (ORP) - 60ml

230mV solution is used as a reference fluid to determine the accuracy of the mV (ORP) probe.

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.
