Calibrating Millwakee 120 PH meter

[ludiNano]

Hey just seting up my Millwakee SM- 120, and the instructions dont'say anything about using the PH 10 solution. Im useing Pinpoint calibration solution.

Do i use the
7.0 and adust the offset then use

10.0 and adjust the slope or 7.0 slope -- 10.0 offset???

Mine is not a Milwaukee but mine is done like this.

Measure the pH of buffer 7, adjust the offset so the meter reads the correct pH for the buffer 7 at that particular temperature.

Measure the pH of the second buffer & adjust the meter reading using the slope adjustment.

Hope it helps.
