Sensible size bottles of buffer for a good price
Regular calibration of any pH meter with accurate buffer solutions is esssential for getting accurate pH readings. These buffers are supplied in sensible black plastic bottles and the solutions have different colours (pH 7 is green, pH 4 is red) to avoid mix-ups. Much easier than dissolving up powders to prepare your own solutions.

Not concentrated, only for very small use
Tested the ph of the acid, with strips=Nearer pH5. Use the whole bottle in about 50L with no visible effect.
