Got a new Milwaukee economy Ph meter for X-mas and was given the 4.01 solution to calibrate.
The directions says this 1 point calibration unit should be calibrated with the 7.01 solution. Couldn’t I use the 4.01 solution to calibrate since 4.01 is closer to the Ph we test for in the mash? Or should I stick with the 7.01 solution and just order a bottle of that solution?
I am in no rush as I am not brewing for a couple weeks yet, but want to be as accurate as I can be with what I am working with.
