The HI10482 HALO is a Bluetooth Smart (Bluetooth 4.0) pH and temperature electrode with Hanna’s Clogging Prevention System (CPS).
This electrode has a unique ground glass junction coupled with a PTFE sleeve to prevent particulates within a sample from clogging the junction. In addition to the specialized junction, the HI10482's glass body and spherical sensing bulb make it ideal for use in a wide variety of applications. All readings are transmitted directly to the HI2202 edgeblu or a compatible Apple or Android device running the Hanna Lab App.
Since the features of the HI10482 HALO electrode are of great benefit to winemakers, the average pH of wine has influenced the choice of calibration buffers when paired with a compatible meter. Generally, a pH between 3 and 4 is optimal for most wines. To increase accuracy and ensure the expected readings are bracketed between the calibration points, pH 3.00 calibration buffer is displayed in lieu of pH 4.01 buffer when this application-specific HALO is connected to the Hanna Lab App.
Easily connect to the Hanna Lab App at the press of a button via Bluetooth wireless technology.
Visible from a distance, the LED “halo” light flashes to indicate the status of the probe.
The HALOs CR2032 lithium ion battery is easily replaceable and lasts for approximately 500 hours.
The HI10482 HALO is a revolutionary pH electrode that incorporates Bluetooth® Smart (Bluetooth 4.0) wireless technology with an application-specific design. This double junction electrode has many features that make it ideal for use throughout a wide variety of industries, including wine. These features include General Purpose (GP) glass, spheric bulb design, integrated temperature sensor, glass body, and is refillable with 3.5M KCl fill solution electrolyte.
General Purpose (GP) glass, as the name implies, is a standard glass formulation that is used for general use. A pH electrode with GP glass will have a resistance of 100 megaohms at 25°C and is suited for measuring pH of samples that are at ambient temperatures. The HI10482 is suitable to use with wine samples that measure from 0 to 80°C (32 to 176°F).
The spheric bulb is for general purpose use within laboratory environments and applications that measure aqueous solutions, such as wine, due to its large surface area. Other tip shapes include conic for penetration and flat tip for surface measurements.
HI10482 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 membrane potential as predicted by the Nernst equation. By having an accurate reading it is possible to provide a temperature compensated reading. Having a built in temperature sensor is important in wine since the measured pH values are more than 3 pH units away from the isopotential point. The further away from the isopoetntail point the greater the influence that temperature has on the observed reading.
The glass body of the HI10482 is ideal for wine analysis use. Glass is resistant to many harsh chemicals and is easy to clean wine stains from. The glass body also allows for a fast transfer of heat to the internal reference electrolyte. The mV generated by the reference cell is temperature dependent, so the faster thermal equilibrium is reached, the steadier the reference potential.
Clogging Prevention System (CPS) technology is an innovation for the improvement of pH measurements in wine juice and must samples that have a high solids content. Conventional pH electrodes use ceramic junctions that can clog quickly when used in samples with high solids content. When the junction is clogged, the electrode does not function properly and erratic readings are the result. The CPS technology utilizes ground glass junction coupled with a PTFE sleeve to prevent clogging. The ground glass allows proper flow of the liquid, while the PTFE sleeve repels solids. As a result, pH electrodes with CPS technology take up to 20 times longer to be fouled as compared to conventional electrodes. When the electrode becomes fouled the PTFE sleeve can be moved to clean the ground glass surface rejuvenating the junction and extending the probe life.
HALO pH electrodes can connect with HI2202 edgeblu meter or a compatible Apple or Android device running the Hanna Lab App.
The Hanna Lab App turns a compatible Apple or Android device into a full-featured pH meter when used with the Hanna HALO pH probe with Bluetooth Smart technology. 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.
The Hanna Lab App incorporates a probe calibration using up to five pH buffers that are automatically recognized and temperature corrected to 25.0ºC during calibration. To increase measurement accuracy and bracket expected readings between the calibration points, pH 3.00 calibration buffer is displayed in lieu of pH 4.01 buffer when this application-specific HALO is connected to the Hanna Lab App.
Display of pH and temperature updated every second. Readings are automatically saved to a history file every hour, limited only by the available memory on the device.
Measurement can be displayed with tabulated data or a graph on the display. The graph axes may be expanded using pinch-to-zoom technology for enhanced viewing.
Connecting the HALO probe to the Hanna Lab App is simple. Tap the Bluetooth icon in the top-right corner to view all available HALO probes then press the button on your HALO probe. Select the newly discovered HALO probe from the list of available probes. If a previously associated probe is in discovery mode when the app is opened it will connect to that probe automatically.
Displays date and time of current calibration, probe offset, and average slope, along with calibrated buffers, mV values, temperature and slopes between each buffer.
The Hanna Lab App alerts you when HALO needs calibration or if a measurement threshold is exceeded.
Saved log files may be annotated with measurement-specific information. Data is easily shared via email in CSV format.
Demo probe mode helps you explore features of the Hanna Lab App. General app information, General HALO information, pH tutorial, maintenance tutorial, and contact information are available in help.
