Can two ORP electrodes be placed in the same container for measurement at the same time?
Thread Content
I was at the client’s site today, where they placed two ORP electrodes in the same container to take measurements. The readings obtained were inaccurate, but when each electrode was measured separately, the values returned to normal. I would appreciate some advice from those with more experience; thank you!
This is because you have a single ORP electrode. If there is a reference electrode, then it won’t happen.
Could you please tell me what the reason is for this? Why can’t they be placed together?

It’s not just ORP electrodes; electrodes such as PH electrodes as well will interfere with each other if placed in the same small container. It’s like in a sealed container, pressure cannot be used to measure level; instead, differential pressure is required. Therefore, in some harsh operating conditions, an additional reference electrode is required, or even two. Generally, just one single one is sufficient for testing.
