Free yourself from wires when performing pH measurements. Hanna Instruments is proud to introduce edge®blu, a pH meter that uses pH electrodes with Bluetooth® Smart technology (Bluetooth 4.0). These pH electrodes connect wirelessly to edge blu or a compatible Apple or Android® device running the Hanna Lab App.

  • edge®blu uses HALO™ Bluetooth pH electrodes with a built-in temperature sensor to send measurement data wirelessly to the meter or a compatible Apple or Android device running the Hanna Lab App.
  • edge®blu features advanced pH electrode diagnostics to ensure worry free measurements. Diagnostics include Hanna’s exclusive CAL Check feature that alerts users to potential problems during calibration.
  • edge®blu features a capacitive touch keypad that gives a distinctive, modern look. The keypad is sensitive enough to be used with laboratory gloves and has a fast response.

The edge®blu is thin and lightweight, measuring just 0.5” thick and weighing less than 9 ounces. edge blu has an incredibly wide viewing angle, 5.5” LCD and a sensitive capacitive touch keypad. edge®blu is simple to configure, calibrate, measure, log and transfer data to a computer or a USB drive. This meter features Hanna’s exclusive CAL Check™ to warn if the HALO pH electrode being used is not clean or if your buffers are contaminated during calibration. An Indicator is also displayed after calibration showing the overall probe condition that is based on the offset and slope characteristic of the pH electrode.

The versatile design of edge®blu makes equally at home in your hand, on a lab bench, or mounted on a wall.

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.

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.

Large, Easy to Read LCD edge®blu features an LCD that measures 5.5” and is clearly viewable from over 5 meters. Add to that a wide viewing angle of 150 degrees and you have one of the clearest LCDs in the industry. In addition to its large LCD, edge® also features full text guides displayed on the bottom of the screen. There is no need to decipher scrambled abbreviations.

Capacitive Touch edge®blu features sensitive capacitive touch buttons for accurate keystrokes when navigating edge’s menus and screens. Since they are part of the screen, the buttons can never get clogged with sample residue.

Bluetooth Digital pH Electrodes edge®blu uses HALO® Bluetooth digital pH electrodes. Once a probe is connected, all sensor information including sensor operating specifications and calibration information is transferred. pH electrodes are easy to exchange when you want to change from measuring with one type to another without the need for recalibration.

Up to Five-Point pH Calibration In standard mode, edge®blu can be calibrated automatic up to 5 points with 7 standard buffers (1.68, 4.01, 6.86, 7.01, 9.18, 10.01, 12.45) and 2 custom buffers.

Good Laboratory Practice (GLP) feature The GLP data can be review at anytime at a push of a button. GLP data includes, date, time, buffers, offset and slope of the last pH calibration.

CAL Check pH Electrode Monitoring Technology Hanna’s exclusive CAL Check feature analyzes the pH electrode response in the pH buffers during the calibration process to alert the user of potential problems such as contaminated buffer and clean electrode. After calibration, indicators for probe condition is displayed on the measurement screen. The probe condition is based on offset and slope characteristics of the pH electrode.

Multiple Data Logging Modes Log-on-demand, log-on-stability, and interval logging modes are all available. Up to 200 data points can be logged on demand and an additional 200 data points for samples logged upon a stable reading. Interval logging is adjustable from 5 seconds to 180 minutes. Up to 600 records can be stored in a maximum of 100 interval lots. Logging modes can be started from the meter or by simply pressing the button on the HALO® pH probe.

Dual USB Ports edge®blu can be connected to a computer or USB flash drive for transferring logged data. The micro USB port can also be used to charge the meter.

Rechargeable Battery edge®blu has a built in rechargeable battery that is charged when the meter is in the plugged in benchtop or wall mount cradle. The battery can also be recharged through the micro USB port with either a USB port from a computer or directly to the power supply.
