Worth knowing before you order
A pH electrode and a buffer pouch are supplied; the electrode is a consumable and the meter's own diagnosis routine is how you tell when it is finished. For field use, budget the things the accessories list omits: electrode storage solution (a pH electrode carried dry in a case will not survive), spare buffer sachets, and the third calibration buffer. The catalogue calls this a pH/ORP meter in its index and the meter does read mV, but no ORP electrode is supplied. The auto-power-off time is printed as 30 minutes in the specification table and 15 minutes in the feature list; the table figure is the one reproduced above.Specification
