Conventional electrodes are normally single junction.
As depicted by the figure above, these electrodes have only a single junction between the internal refernce wire and the external solution.
Under adverse conditions, such as high pressure, high temperature, highly acidic or alkaline solutions, the positive flow of the electrolyte through the junction is often reversed resulting in the ingress of sample solution into the reference compartment.
If this is left unchecked, the reference electrode can become contaminated, leading to complete electrode failure.
Another potential problem with single junction electrodes is the clogging of the junction due to silver chloride (AgCl) precipitation.
Silver can be easily precipitate in samples that contain Tris buffer, sulfides or heavy metals.
When the electrolyte solution makes contact with the sample, some AgCl will precipitate on the external face of the junction.
The result is drifty readings obtained from the sensor.

Hanna’s double junction system, as the name implies, has two junctions, only one of which is in contact with the sample as shown in the figure.
Under adverse conditions, the same tendency of sample ingress is evident.
However, as the reference electrode system is separated physically from the intermediate electrolyte area, the contamination of the electrode is minimized.
The likelihood of clogging of the junction is also reduced with a double junction electrode since the outer reference cell uses a fill solution that is “silver-free”.
Since there is no silver present, there is no precipitate forming to clog the junction.

HALO™ pH electrodes with Bluetooth® Smart Technology
HI2202-0 wireless ph meter and ph electrode

Each edgeblu HI2202-02 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.

Auto-Detection
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.

            What is pH?

            A pH (potential of Hydrogen) measurement reveals if a solution is acidic or alkaline (also base or basic).
            If the solution has an equal amount of acidic and alkaline molecules, the pH is considered neutral.
            Very soft water is commonly acidic, while very hard water is commonly alkaline, though unusual circumstances can result in exceptions.
            The pH scale is logarithmic and runs from 0.0 to 14.0 with 7.0 being neutral. Readings less than 7.0 indicate acidic solutions, while higher readings indicate alkaline or base solutions.
            Some extreme substances can score lower than 0 or greater than 14, but most fall within the scale.

            What is automatic temperature compensation (ATC)?
            When measuring pH using a pH electrode the temperature error from the electrode varies based on the Nernst Equation as 0.03pH/10C/unit of pH away from pH7.
            The error due to temperature is a function of both temperature and the pH being measured.
            Temperature compensation can be achieved manually or automatically.
            Manual temperature compensation is usually achieved by entering the temperature of the fluid being measured into the instruments menu and then the instrument will display a "Temperature Compensated" pH reading.
            Automatic temperature compensation requires input from a temperature sensor and constantly sends a compensated pH signal to the display.
            Automatic temperature compensation is useful for measuring pH in systems with wide variations in temperature.
