FLAIR FORM pH TEST KIT with bottle and vial is super concentrated and only requires ONE drop per test – approximately 800 tests included. Reliable and fast pH readings, unlike electronic pH meters, there is NO complex or costly maintenance required with the pH Test Kit. pH range 4.0 to 8.0: Many pH testers do not operate below pH.
Note that pH meter electrodes usually need to be left in the sample for several minutes before an accurate/ stable reading is produced.
When using a pH Test Kit you will get accurate results every time. Even if electronic pH meters are properly maintained, they are still susceptible to error because lower quality electrodes respond to foreign ‘species’ (e.g. sodium). For this reason, if using an electronic pH meter, occasionally cross check your readings with a pH Test Kit.
