Another ORP Question RE: Calibration

[gman2]

I just bought the Aquadyne calibration kit for my Neptune controller since I could not find that quinhydone stuff. The kit came with it and I calibrated the probe.

Now my question is who knows what the readings should be in the quinhydrone solution of ph4 and ph7?

I just want to know it for reference and could not find my answer anywhere.

Thanks
Tony
