My wife has just given me a pH-107 pocket meter and it comes with two sachets a pH 4.00 and a 6.86 pH powders .
The instructions to calibrate are as follows.
Immerse the tester up to the maximum e immersion level in pH 6.86 buffer solution.
Allow the reading to stabilize and a just the calibration trimmer to read 6.9.
But this is where I need to know what amount of water to use with the buffer powder and what type of water to use.
Can some one please help as this tool sounds like it is going to be a big asset to me.
Thank you
Derek
