Hanna Instruments is proud to introduce the world's most innovative pH meter...edge™.

Edge is thin and lightweight, measuring just half an inch thick and weighing less than 9 ounces, edge has an incredibly wide viewing angle, 5.5 inch LCD and a sensitive capacitive touch keypad.

Edge measures pH, conductivity and dissolved oxygen through its unique digital electrodes. These digital electrodes are auto-recognized. Providing sensor type, calibration data and a serial number, and they connect to edge with an easy to plug-in 3.5 mm connector. Edge's versatile design is equally at home in your hand, on a lab bench or mounted on a wall. Edge simplifies measurement, configuration, calibration, diagnostics, logging and transferring data to computer or a USB drive.

Edge features Hanna's exclusive CAL-CHECK® to warn you if the electrode you are using is not clean or if your buffers are contaminated during calibration. We have also added to CAL-CHECK for sensors with matching pin: now it warns you if the pH bulb is cracked, and if the junction of the electrode is compromised.

Edge is the culmination of Hanna's vision, design capabilities, integrated production facilities, and world class R & D teams. With edge, Hanna has set the new standard!

Two USB Ports: Edge includes one standard USB for exporting data with a flash drive. Edge also includes one micro USB port for you to connect to a computer for file export and for charging your edge when the cradle is not available.

Large, Easy to Read LCD: Edge features a 5.5 Inch 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.

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.

Great Design: Edge is incredibly thin and lightweight, measuring just 1/2 Inch thick and weighing just 8.8 ounces.

Capacity Touch Buttons: Edge features a capacitative 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).

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 optimum viewing angle.

Basic mode: you can use Edge in Basic Mode, ideally for routine measurements for a simplified screen and features

GLP: Data of the last calibration you perform is stored in the sensor: electrode's offset, slope, date, time and buffer/standards. When any sensor (pH, EC or DO) is connected to the edge, GLP data is automatically transferred.

CAL-CHECK®: Edge features Hanna's exclusive CAL-CHECK to warn you if the bulb of the electrode is not clean or if the buffers are contaminated during calibration.

Zero Footprint: 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.

Data Logging: Edge allows you to store up to 1,000 log records of data. Data sets include readings. GLP data, date and time.

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.

Digital Smart Electrodes: The electrodes used with edge are nearly as advanced as the edge itself: featuring a built-in microchip that stores sensor type, ID, and calibration information that is automatically retrieved by edge once the electrode is plugged in.

Stored pH calibration information includes: calibrated buffers, date, time, offset and slope characteristics of the electrode. Conductivity calibration information includes: calibrated conductivity standards, date, time and cell constant of the sensor. Dissolved oxygen calibration information includes: standards used for calibration, date, time, altitude and salinity correction.

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 pin settings.
