Measuring pH value and ORP with Hanna Instruments – recording of Aquacentrum insider conversation

Does it make sense to measure the pH value and the redox potential with an electrical measuring device?

Electrical measuring devices no longer show reliable values ​​for basic ionized active water with a redox potential of less than -200 mV.

With extremely antioxidant, hydrogen-rich water, you can “go blind” so to speak, and the measuring electrodes have to be replaced.

We created a video in our water room, which consists partly of sound and partly of video content.

This is the globally recognized method to determine the antioxidant activity of water containing H2 (basic or not):

This makes it reliable and absolute. The redox potential ORP is not that important, please see the following video:
