Thanks Tom, I'll certainly give this a try. Will make my bought test
solution go a lot further.

Hello Roger,
I made 2 calibration solutions. I first used the supplied calibration
solution to calibrate my meter. Then I mixed my solutions and
tested them.
This gives me a primary calibration, and two secondary check points.
I put 1 ml of PH 7 test solution in 499 ml of my tap water. This
gives me
123 uS.
I then put 1 ml of PH 7 test solution in 499 ml of distilled
water. This
gives me 30 uS.
Since I use PH meters a lot, I have a lot of the test solutions and
keep
them fresh. I don't know if the conductivity will vary from batch
to batch,
but I will have to go through a liter of my test solution before I
will find
out.
Tom

Just as a matter of interest. Does anyone know how to make/mix the
calibration solution for a pH meter?
