Hanna Instruments is proud to introduce the world’s most innovative pH/ORP meter: edge®.
edge’s groundbreaking design is the culmination of Hanna’s vision, design capabilities, integrated production and world class R&D. edge is a single meter that can measure pH and ORP and is incredibly easy to use.
edge® pH/ORP is packed with many cutting edge features to ensure accuracy and usability.
Digital pH Electrodes
edge pH electrodes are highly advanced, featuring a built-in microchip that stores calibration information that is automatically retrieved by edge once the electrode is plugged in. With a digital electrode it is possible to change electrodes without having to recalibrate since the calibration information is stored in the pH electrode and not the meter. This allows flexibility for the user that measures pH with more than one electrode.
Hanna’s exclusive CAL Check feature analyses the pH electrode response in the pH buffers during the calibration process to alert the user of potential problems. Indicators include contaminated buffer and clean electrode. After calibration indicators for probe condition and response time are displayed on the measurement screen. The probe condition indicator is based on offset and slope characteristics of the pH electrode.
When used with Hanna’s electrodes equipped with a matching pin, edge constantly checks the impedance of the pH measuring electrode to notify you in real time in the event of glass breakage. During calibration, Sensor Check checks the state of the junction. The reference junction is also evaluated and reported on the display.
