Bought this set for a brewery and they are exactly what I needed for PH testing.

We bought this to calibrate our ph meter for our hot sauce before bottling. I like that there is alot solution instead of a one time packet. Thank you again

I use this solution to calibrate all of my various ph meters & it works as it should. The solutions are the accurate ph. I have not tried to use it to calibrate the one meter I have that requires slightly different ph levels than the ones included.

pH 7.00 buffer arrived in a leaking bottle. Fortunately, the bottle was sealed in a plastic pouch to protect the packaging from being soaked by the buffer fluid. It was still highly disappointing for the calibration buffer to arrive in such a messy state.Biopharm Buffer Calibration Solution Kit 3-Pack of 500 ml each pH 4, 7 and 10 Calibration Standards Color coded NIST Traceable For All pH meters
