Go to www.coleparmer.com They will have calibration/buffer solution. Get the 7.0 or 7.1 fluid.

Buffer Water for PH Testing

Bought a PH Tester at Graingers the other day. Of course when I open it up, it says I need a buffer to calibrate it.

Where do I get this, Graingers?

Thanks,

I have to assume that the tester is reasonably calibrated from the factory, but things happen and they'll likely suggest calibration against some sort of known ph value.

Google "ph distilled water" and "ph deionized water" to see just how difficult it can be to find a reference source.

Will this work?
