Can we help you?

Edge blu utilizes Bluetooth Smart technology (low energy) for outstanding battery life and can operate up to 10 m (33’) from the compatible HI11102 HALO pH electrode for versatile measurement in the lab or field.

Edge blu is thin and lightweight, measuring just 0.5” (12 mm) thick and weighing less than 9 ounces (250 g). edgeblu has an incredibly wide viewing angle, 5.5” (14 cm) LCD and a sensitive capacitive touch keypad. 

Portable field unit

edge blu is ideal for field use due to its light weight, large screen, and thin design. It can easily be slipped into a backpack or messenger bag. The battery life lasts up to 8 hours when used as a portable device.

Wall–mount cradle

The included wall–mount cradle makes it easy to conserve space on the benchtop while also charging edge blu with the AC adapter. The cradle is ideal for continuous monitoring applications.

Electrode holder with built-in cradle

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

Technical Features

Two USB ports

edge blu includes one standard USB for exporting data to a flash drive. edge blu also includes one micro USB port for exporting files to your computer as well as for charging when the cradle is not available.

Data logging

edge blu allows you to store up to 1000 log records of data. Data sets include readings, GLP data, date, and time.


Data of the last calibration you perform is stored in the sensor including the date, time, and buffers used. When the sensoris connected to edge blu, GLP data is automatically transferred.


edge blu features Hanna’s exclusive CAL Check™ technology to warn you if the electrode bulb is not clean or if the buffers are contaminated during calibration.


Capacitive touch keypad

edge blu 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

Easy to read LCD

edge blu 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.
