HI98107 pHep® Waterproof Pocket pH Tester
with 0.1 pH Resolution

The Hanna Instruments HI98107 pHep® pH tester is a rugged and reliable pocket-sized tester for use in the lab or field. This modern looking meter is only 0.7" thick and extremely ergonomic, fitting comfortably in your hand. This tester keeps things simple with a two-button operation; one for ON/OFF, the other for Calibration.
•Large, Easy-to-Read Display
•Simplified Two Button Operation
•Extractable Cloth Junction to Extend pH Electrode Life

The HI98107 tester features a large multi-level LCD which displays both pH and temperature readings simultaneously. The pH readings are displayed with a 0.1 pH resolution and with an accuracy of ±0.1 pH. The pH range of the HI98107 is from 0.0 to 14.0 pH. An exposed temperature sensor allows for rapid automatic temperature compensated pH measurements. Temperature can be set to display in ℃ or ℉. The LCD screen has stability and calibration tag indicators. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.

The pH electrode uses a unique reference cell design that utilizes an extractable cloth junction. A clogged junction will typically exhibit erratic readings that will not stabilize. Simply extracting a small portion of cloth from the meter will clear any clog by exposing a fresh, clean surface. The ability to clear any clogging will extend the life of the pH electrode.

Calibration is performed by pressing the dedicated calibration button. Once in calibration mode the pH electrode can be calibrated to 1 or 2 points using the pre-programmed standard buffers (pH 4.01, 7.01,10.01). When the standard value is recognized and stability is reached, the meter automatically accepts and stores the calibration value.

Setup options include automatic shut off timing and temperature unit displayed. Automatic shut-off options are to turn the meter off after 8 minutes, 60 minutes, or disabled. To enter the setup mode the user presses a button located in the battery compartment.

HI1230B  Gel Filled PEI Body pH Electrode with BNC Connector

The HI1230B is a PEI body, double junction pH electrode with a BNC connector.

This electrode has a single ceramic junction in the outer reference cell and the spherical pH sensing portion is made with general purpose glass and is protected by an extension of the durable PEI body.

This design consideration is ideal for field applications as well as general purpose use.
•Durable PEI Body
•Double Junction Reference
•General Purpose (GP) Glass

Standard probe included in the delivery.

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

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.

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.
