A combination pH buffer kit with 5 x 20ml sachets of pH 4.01 and 5 x 20ml sachet of pH 7.01

Ideal for those requiring an accurate acid or neutral reading, particularly suitable for those working in education and in any environments where the pH is expected to be acid or neutral.

The single dose sachets are really handy with each sealed sachet holding just the right amount of solution. Each time a meter or electrode is calibrated using the Hanna sachets, it is like using a newly opened bottle of solution!

Simply tear off the top and insert pH electrode or tester into the sachet.
