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, Conductivity, Dissolved Oxygen and is incredibly easy to use. We put a lot of thought into edge’s ease of use.
Large Easy to Read LCD
edge features a 5.5" LCD display that you can clearly view 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.
Capacitive Touch
edge 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).
Clear Full Text Readout
edge features clear, full text guides 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® is packed with many cutting edge features to ensure accuracy and usability.
Digital Electrodes
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 settings.
Sensor Check
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.
3.5 mm Probe Input
Plugging an electrode in has never been simpler, no alignments, no broken pins, just connect the 3.5 mm plug and get started.
edge® is incredibly versatile. It can be used in a variety of ways and in a variety of environments without taking up the space of a traditional benchtop meter.
Wall Mount
Using the wall mount cradle (included), edge can be placed on a wall, leaving zero footprint on the benchtop space. The cradle has a built in connector to power edge and charge its batteries. edge's zero footprint is designed to save you valuable benchtop space.
Cradle and Electrode Holder
edge is equipped with a benchtop cradle with an adjustable swivel electrode holder to charge and hold the edge securely in place at the optimium viewing angle.
edge® is incredibly thin and weighs only 8.8 oz., has an 8 hour battery life, and dual USB inputs.
Two USB Ports
edge includes one standard USB for exporting data with a flash drive and a second micro USB port for you to connect to a computer for file export and for charging your edge when the cradle is not available.
Data Logging
edge allows you to store up to 1000 log records of data. Data sets include readings, GLP data, date and time.
Basic Mode
You can use edge in Basic Mode, ideally for routine measurements for a simplified screen and features.
