The FC2022 is revolutionary pH electrode that incorporates Bluetooth Smart (Bluetooth 4.0) wireless technology with an application specific design. This electrode has many features that makes it ideal for measuring food related products. These features include: low temperature (LT) glass, conical bulb, food grade PVDF body, and open junction with viscolene gel electrolyte.
Low Temperature Glass Formulation
The glass tip uses a special Low Temperature (LT) glass formulation with a lower resistance of approximately 50 megohms compared to General Purpose (GP) with a resistance of about 100 megaohms. This is beneficial since many food products are stored at low temperatures. As the temperature of the glass decreases in the sample, the resistance of the LT glass will increase approaching that of GP glass at ambient temperatures. If using GP glass, the resistance would increase above the optimum resistance for the high impedance input of a pH meter.The FC2022 is suitable to use with samples that measure from 0 to 60°C.
Conical Glass Tip
The conical shaped tip design allows for penetration into solids, semi solids, and emulsions for the direct measurement of pH in food products including meat, cheese, yogurt, and milk.
Built-In Temperature Sensor
FC2022 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.
Polyvinylidene fluoride (PVDF) is a food grade plastic that is resistant to most chemicals and solvents, including sodium hypochlorite. It has high abrasion resistance, mechanical strength and resistance to ultraviolet and nuclear radiation. PVDF is also resistant to fungal growth.
Open Junction Reference
The open junction design consists of a solid gel interface (viscolene) between the sample and internal Ag/AgCl reference. This interface not only prevents silver from entering the sample, but also makes it impermeable to clogging, resulting in a fast response and stable reading.
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.
Help & Tutorials
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.
