Simple or Precision Mode to Suit all Operations

Hanna Instruments proudly introduced one of the the world’s most innovative pH meters: edge^®. This hybrid meter’s groundbreaking design is the culmination of Hanna’s vision, design capabilities, integrated production and world class R&D.

The edge meter is only 0.5” thick yet rich in features to accommodate the needs of a vast amount of customers. For those that prefer very simplistic operation there is a basic mode operation with simplified menu and options while for those who require advanced features there is the full featured standard operating mode.

The HI2020 pH kit can be upgraded at any time with additional probes to measure Conductivity or Dissolved Oxygen and as edge features a 5.5” LCD display it can be  you clearly viewed from over 5 meters.

The large display and it’s wide 150° viewing angle provide one of the easiest to read LCD’s in the industry. It also features a capacitive touch keypad that gives a distinctive, modern look. Since the keypad is part of the screen, your buttons can never get clogged with sample residue. The up and down keys move faster when continuously held (ideal for scrolling through numerous logs).

Full text guides are displayed on the bottom of the screen. There is no need to decipher scrambled abbreviations or symbols; these helpful messages guide you through every process quickly and easily. edge 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. These digital electrodes also feature an easy to plug in 3.5 mm connector so you never have to worry about the right angle or aligning pins. 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.
