Is there a household product to verify ORP calibration?

Hi as per the title, I don't have any more ORP calibration liquid on hand and would like to see that my Milwaukee ORP controller is measuring correctly. H2O2? Purified water ? 70% alcohol....anything with a known ORP to check ? Thank you

Not really. I’d get a commercial standard.

I do remember seeing an item on Amazon for calibrating the ORP probe. It's a reference solution.

Is there a household product to verify ORP calibration?
