This meter pH can measure ion concentration and ORP in the mV range. The meter is housed in a rugged, waterproof, ABS casing that is built to last.
The Auto-Instruction feature guides the user step-by-step through the calibration process with graphic symbols. Unlike conventional microprocessor pH meters that offer only the standard pH buffer solutions of 4.01, 7.01 and 10.01 for calibration, this meter also allows calibration at the important NBS (NIST) buffers of 6.86 and 9.18. Because the electrode requires a certain amount of time to stabilize between buffers, the meter will display the READY symbol only when the electrode has stabilized.
The powerful software integrated in this meter will allow 1 or 2 point calibration using any of the 5 memorized buffers. This is an important feature in field measurements, since if you end up with access to only one pH buffer, you can always perform the calibration in at least one point. This meter also features a user-selectable automatic shut-off to save battery life.
