This is the same pH meter as the pH56 model, but with a lower resolution (0.1 pH) and a more affordable price tag.
Includes one set of calibration solution sachets. Frequent calibration will ensure you always have the most accurate read on your water. Addtional sachets are available in both 4.01 and 7.01 buffer solutions. Solutions are also available in 220 ml bottles.
Please note that electrodes must be rinsed after use and stored in electrode storage solution to ensure proper function of the meter. Storage solution is available in 230 ml bottles.
