    Did you mix quinhydrone powder into those solutions, or did you just use straight pH4 and pH7 solutions?

    It's not easy to source and is very expensive. Unless you are using ORP in an accuracy critical purpose (like controlling an ozone reactor), I would just contact support and get instructions on how to reset the probe calibration back to factory. In most cases, ORP is a relative value and does not require calibration.
