ph meter and ppm meter calibration?

i just picked up a ph tester and a ppm tester and the solutions so this may be a stupid question but do i just use the solutions by themselves to calibrate them or do i have to mix it with water or something...no directions and dont watn to fuck it up ;/

Just use the solution that they came with. No mixing. Use the small screw driver (if it's manual), to adjust the pH or PPM to what the solution package says. Let it sit in the solution for a couple minutes to make sure it's steady and not fluctuating up or down. Then remove it and power down and you are all set. The solution basically tells the tester "Hey, this is what 1500ppm feels like.....or.......this is what 7.0 pH feels like. Hope this helped some.

yes it did thanks alot i just wasnt sure if i was supposed to mix the solutions with water or something but thanks now i know

I have a question.

I got my meter and it came with this small packet of buffer solution of 7.0.

To avoid buying more solution, would it be reasonable to calibrate the meter with the buffer solution, then just find some water, get that to 7.0 and keep that water around?

Basically will my created buffer solution change, or will it stay at what I adjusted it to?

i calibrate mine with distilled water. a buck a gallon.

Have you tested distilled against a buffer solution? Is it always spot on neutral at 7, or is it just close?

One other question, there is no reason for the distilled water.... once you get it to the pH you want anyways to slip to some other value is it?

Well, I took a bottle of water, that set right at about 7.2. I then got it down to right at 7.0, and I'll be using that as a buffer from now on. So as long as the water sitting on the shelf doesn't all of a sudden lose it's 7.0 value that I've set it to, I should be golden.
