Hi. I bought nutradip calibration solution ph7 and I was looking for directions on how to use it, but I cant. Can you give me some direction on how to use your product, thanks.

Here is a link to our Nutradip ph Meter Manual:

On the 2nd page, there is a section on calibrating your meter. These instructions would be specific to Nutradip meters. For other branded meters, please check out their respective manual. All Nutradip calibration solutions are compatible with other branded meters.
