Excellent pH meter
I purchased this because the cheap yellow meter I got was garbage. It was measuring pH of many solutions way off, despite having plenty of ions available (saltwater aquarium for example), and despite measuring both of the included buffer solutions perfectly! This meter is very fast, accurate and easy to use. The 1st day using it was a little slow to stabilize even after following the instructions for rehydrating the probe. My advice is hydrate the probe much longer the 1st time and buy some 3M KCl storage solution as recommended in the manual but not included, keep the probe stored wet and ready to go. From experience working with lab pH meters the storage solution should give you many years of life with minimal calibrations. The included case is nice but you'll need to find another way to store with the probe wet, I keep mine upright in a cup on a shelf, with storage solution in the included cap.
