PH, ORP and EC at the same time?

Hello, it is possible to measure PH (SEN0161), ORP (SEN0165) and EC (DFR0300) at the same time? Or they have to be isolated? thank you

Yes, it is possible to isolate. But when the alt generator and the pump are working, water will flow, so the value will not stable. It is hard to avoid. Maybe you can get a average value .

sorry for the late reply. it is possible to isolate these? it is to be a measuring station for our pool. though I would have liked these 3 measured values. this could be the salt generator and the pump have a negative impact on the measurement results.

It is unable to measure PH (SEN0161), ORP (SEN0165) and EC (DFR0300) at the same time,they have to be isolated。 There should be NO working electrical device in the container. Any tiny leakage of electricity will cause the probe working error. Especially, many people bought the EC meter and put it into the same tank for the test, but then the pH meter cannot work well anymore. Please separate them into different containers, or turning off the EC meter when using the pH meter.
