Worth knowing before you order
A pH electrode, ATC probe and stand are supplied. The feature worth paying for here is the automatic electrode diagnosis: the meter reports the slope and the zero offset after every calibration, which is the only reliable way to know that the electrode — a consumable — is reaching the end of its life before it starts giving quietly wrong numbers. Buffers 4.01 and 7.00 are supplied, so the third calibration point (10.01 on the USA set or 9.18 on the NIST set) needs a separate buffer order, and electrode storage solution is not listed at all — a pH electrode left to dry out is a dead electrode.Specification
