API pH Test Kit The API pH Test Kit uses drops for much more accuracy (and tests!) than strip tests. The test is quick and easy and measures pH between 6.0 and 7.6. If that doesn't cover you then you are going to need API pH up or pH down:) Each kit comes with color scale, drops, instructions, and beaker. 250 tests with each kit!
