A hybrid meter that can be used in portable, wall-mount and benchtop configurations

The versatile design of edge enables it to be used as a portable, wall-mount or benchtop meter. edge simplifies measurement, configuration, calibration, diagnostics, and logging and transferring data directly to a computer or USB drive.

edge Digitally Smart Electrodes

Digital Smart Electrodes

edge measures pH, conductivity, and dissolved oxygen through its unique digital electrodes. These electrodes are auto-recognized and feature a built-in microchip that stores sensor type, ID, and calibration information that is automatically retrieved by edge once the electrode is connected.

Two USB Ports

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

edge Sleek, Portable Design

Sleek, Portable Design

Due to its light weight, large screen and thin design, edge can be easily slipped into a backpack or messenger bag. edge offers up to 8 hours of battery life when used as a portable device.

edge Data Logging

Data Logging

Store up to 1000 log records of data. Data sets include readings, GLP data, date and time. edge offers manual log-on-demand, manual log-on-stability, and interval logging.

edge Wall Mount

Wall Mount Cradle and Electrode Holder with Built-in Cradle Included

The included wall mount cradle makes it easy to conserve space on the benchtop and can charge edge with the AC adapter. Ideal for continuous monitoring applications.

The included electrode holder features an adjustable swivel arm with a built-in cradle to hold edge securely in place at the optimum viewing angle.

Rechargeable Battery

The benchtop or wall-mount cradle can be used to recharge the meter battery. The battery can also be recharged through the micro USB port with either a computer connection or the power supply.

edge Technical Features

edge Basic Mode

Basic Mode

edge Basic Mode is ideal for routine measurements with a simplified screen and features.

edge CAL Check

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.

edge Sensor Check

Sensor Check (using HI12301 and HI11311 only)

When using 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 verifies the state of the junction. The reference junction is also evaluated and reported on the display.

edge GLP

GLP

edge Digital Smart Electrodes feature a built-in microchip to store data of the last calibration performed: 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.

edge Design Features

 
edge Capacitive Touch Buttons

Capacitive Touch Buttons

edgebfeatures a capacitive touch keypad for a distinctive, modern look. Since the keypad is part of the screen, the buttons don't get clogged with sample residue. The up and down keys move faster when continuously held (ideal for scrolling through numerous logs).

 
edge Easy Read LDC

Easy to read LCD

edge features a 5.5” (14 cm) LCD display that you can clearly view from over 5 m (16.4’). The large display, with its wide 150° viewing angle, provides one of the easiest to read LCDs in the industry.

 
edge Probe Input

3.5 mm Probe Input

Plugging an electrode in has never been easier, no alignments, no broken pins, just connect the 3.5 mm plug and get started.

 

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.
