pH (Individual Test Kits)

pH must be controlled and monitored because it plays an essential role in almost all chemical and biological processes.

LaMotte pH Test Kits

Each test kit consists of an Octet Comparator, graduated test tubes, and a bottle of indicator solution for 50 tests. LaMotte Company has been supplying laboratory quality pH indicator tests to professional analysts for more than eighty years; these are the most reliable, economical pH test kits available. Simply fill the tube to the mark with the sample water, add several drops of indicator, and compare the resulting color against the eight permanent color standards in the comparator.

How to Select the Right pH Kit:
Single or Wide Range?

Single range kits cover a range of 1.4 pH units in 0.2 unit increments (0.1 unit sensitivity). Wide range kits may cover as many as 7 pH units in increments of 0.5 or 1.0 pH units (0.25 or 0.5 unit sensitivity).

Which Range?

Choose a kit in which the midpoint of the range covered is as close to the average or optimum pH value of the sample water. If this value is unknown, choose a wide range kit.

Indicators specific to a particular pH range allow colorimetric determination of pH. If the water to be tested is cloudy, one may wish to employ the bicolor reader.
