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.
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.
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, edgeblu 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.
edgeblu 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.
HALO™ pH electrodes with Bluetooth® Smart Technology
Each edgeblu is supplied with a HI11102 HALO™ Bluetooth pH electrode. The Halo uses Bluetooth Smart Technology (Bluetooth 4.0), which is energy efficient and allows the probe to operate on 1 CR2032 battery for approximately 500 hours. The HI11102 HALO pH electrode is a double junction, gel filled, glass body pH electrode with a built-in thermistor temperature sensor. All readings are automatically compensated for temperature variations.
The HI11102 HALO pH electrode transmits measurement data directly to edgeblu or a compatible Apple or Android device. All HALO pH electrodes are auto-detected providing pH sensor type, calibration data and serial number when connected. The HALO pH electrode also features a blue LED ring that changes flashing frequency based on whether it is in discovery mode or when it is connected to the edgeblu or compatible device. The button located on the HALO™ pH probe is used to place it in discovery mode or to log data directly to the edgeblu or compatible Apple or Android device.
Bluetooth Smart Technology
HI11102 HALO pH electrode uses Bluetooth Smart Technology (Bluetooth 4.0). This technology offers low power consumption allowing for a long, 500-hour battery life. The range of the Bluetooth connection is 10 meters (33’) between the probe and receiving device.
At a push of the button on the HI11102 HALO pH electrode places the probe in discovery mode and will be detected by edgeblu or compatible device running the Hanna Lab App. Once connected the serial number, calibration information including date, time and buffers used, and the electrode specifications will be loaded into the meter. Having this information stored in the electrode allows for hot swapping to other pH electrodes without recalibrating. The details of the electrode and calibration information are stored with any logged readings.
pH Electrode Design
The HI11102 HALO pH electrode is a glass body, gel filled, double junction pH electrode that has an indicating probe made with general purpose glass. The glass body is resistant to many chemicals and easy to clean. Being gel filled reduces maintenance since there are no fill solutions to add. The double junction design is suitable for a variety of solutions that can contain substances such as heavy metals or Tris buffer that will cause the silver chloride (AgCl) found in a single junction probe to precipitate and clog the junction. The general purpose glass indicating probe has a temperature range of use from -5.0 to 80.0°C (23.0 to 176.0°F) and for samples that have a 0 to 12 pH.
Built-In Temperature Sensor
The HI11102 HALO pH electrode features a built-in thermistor temperature sensor that is in the tip of the indicating pH electrode. A thermistor temperature sensor provides for a high accuracy temperature reading and should be as close as possible to the indicating pH electrode in order to compensate for the effect that temperature has on the change in resistance of the glass. By having an accurate reading it is possible to provide a temperature compensated reading.
iOS and Android Compatibility
The HI11102 HALO pH electrode is compatible with Apple or Android devices running the Hanna Lab App, available for download at no charge.
The Hanna Lab App turns any compatible Apple or Android device into a full-featured pH meter. Functions include calibration, measurement, data logging, graphing and data sharing. Measurement and logging of pH and temperature at one-second intervals start as soon as the probe is connected. Measurements can be displayed alone on the display, with tabulated data, or as a graph. The graph can be panned and zoomed with pinch-to-zoom technology for enhanced viewing. Any readings that exceed user-defined alarm threshold are highlighted in yellow on the measurement screen, graph, and table. Readings that exceed the pH probe specifications are highlighted in red.
Readings are automatically saved to a history file every hour, limited only by the available memory on the device. Readings in specific time intervals can also be saved. Saved log files may be annotated with measurement specific information and also shared via email in CSV (comma-separated values) format.
