Based on the tests we conducted yesterday, the calibration solutions give satisfactory results. This indicates that the probe is measuring correctly. Additionally, I can see that the measurement readings indicate values around 700 that vary slightly, which is completely normal. What is the second measurement with the ORP meter that you mentioned? (If you compare the pool water directly with the device measurement, you will always have a significant difference due to different concentrations of CO2, CHLORINE, etc.) Please note that ORP measurement is extremely complex. (For example, in the factory, when we need a more accurate measurement, we use quinhydrone.) The most important thing is to maintain a stable redox level.
