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, many growers will choose to occasionally cross check their readings with a Flairform pH Test Kit.
