my ph meter does not have 6.45= 3 digit display just a display that reads 6.4
so my question is how do I calibrate this ph 6.86 solution?do I round it up to 6.9?
I don't have a thermometer yet but I should have one tonight
the solutions I have are 4.0 and 6.86 with a cheap 2 digit display
thanks for the help
