Works

Quality product and good value. Easy to use and very accurate. Performs well.

These came clearly marked and the different colors add to the security of using the correct product for the calibration.

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

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.

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

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
