HALO® Bluetooth® Wireless pH Electrode for Test Tubes - HI13302
The HI13302 HALO is a Bluetooth® Smart (Bluetooth 4.0) pH and temperature electrode made specifically for the pH measurements of test tubes and vials. This electrode is composed of a glass body and spheric, general purpose glass sensing bulb. The double junction design ensures that the gel electrolyte is free of silver chloride (AgCl) between the sample to be measured and the internal reference cell, resisting clogging and any potential precipitation at the junction. All readings are transmitted directly to the HI2202 edgeblu or a compatible Apple or Android device running the Hanna Lab App.
One Press Connect
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 HALO® Wireless pH probe incorporates Bluetooth Smart technology® Smart technology with an application-specific design. This electrode features include general purpose (GP) glass, spheric bulb, integrated temperature sensor, and a slim glass body that fits easily into a test tube or a vial.
General Purpose Glass Formulation
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 from -5 to 50°C (23 to 122°F).
Spheric Glass Tip
The spheric bulb is for general purpose use within laboratory environments and applications that measure aqueous solutions due to its large surface area. Other tip shapes include conic for penetration and flat tip for surface measurements.
Built-In Temperature Sensor
HI13302 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.
5 mm Glass Body
The glass body of the HI13302 is only 5 mm in diameter allowing for the measurement of pH in test tubes and other small vials.
Double Junction with Open Reference
The HI13302 is a double junction design. pH electrodes are available as single junction or double junction. A double junction pH electrode uses 3.5M KCl in the outer reference, which does not react Tris buffer or metal to cause a precipitate that would clog the junction. The HI13302 has an open outer reference junction that also resists clogging and requires very little sample to take a measurement.
Hanna Lab App
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.
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.
Fluid, Dynamic Graphing
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.
GLP (Good Laboratory Practice)
Displays date and time of current calibration, probe offset, and average slope, along with calibrated buffers, mV values, temperature and slopes between each buffer.
Calibration Reminder & Measurement Alarms
The Hanna Lab App alerts you when HALO needs calibration or if a measurement threshold is exceeded.
Log & Share Data
Saved log files may be annotated with measurement specific information. Data is easily shared via email in CSV format.
