5.3 Probe calibration
The ORP probes require a calibration before their first use and then they need to be
calibrated periodically. It is because different probes can have different answers and
because the response of the same probe inevitably varies with time.
The calibration consists of measuring the response of the probe introducing it in two
buffer solution and recording this response in order to deduct the ORP (RH) of any
other solution, in our case, the ORP (RH) of the water in the pool.
The calibration of the probe is carried out using a buffer solution supplied (220mV)
