Built-in Microchip
The built-in microchip stores sensor type, serial number and calibration information including date, time, offset, slope, probe condition and buffers used. This information is automatically retrieved by edge® once the electrode is plugged in. The ability to transfer information allows for hot swapping of probes without having to recalibrate. All pH measurements are performed within the electrode and transferred digitally to the meter. This overcomes any noise issues associated with the traditional high impedance analog measuring system. Electrical noise can be generated from a built in temperature sensor and while working in a humid environment.Spherical Glass Tip
The spherical shaped tip design allows for a wide area of contact with the measured sample. This permits a faster electrode response with a higher degree of stability. The HI10480 utilizes a general purpose (GP) glass formulation, which has a resistance of approximately 100 megaohms. This means that measuring conditions are optimal around ambient temperatures. Use of high temperature or low temperature glass around ambient temperatures would not be optimal due to a long response time or a shortened lifespan of the electrode.CPS Sleeve Junction
CPS™ (Clogging Prevention System) is an innovation in electrode technology. Conventional pH electrodes use ceramic junctions that clog quickly when used in wine. When the junction is clogged, the electrode does not function. CPS™ technology utilizes the porousness of ground glass coupled with a PTFE sleeve to prevent clogging of the junction. The ground glass allows proper flow of the liquid, while the PTFE sleeve repels dirt. As a result, pH electrodes with CPS™ stay fresh up to 20 times longer than conventional electrodes.Double Junction Reference
A double junction electrode has an internal compartment surrounding the reference wire. Silver ions are present in the electrolyte of the internal compartment, which houses the Ag/AgCl reference wire; the electrolyte outside this compartment is silver free. The double junction design means that virtually no silver from the electrode enters the sample. This design allows measurement in applications where silver ions in the sample are undesirable or silver precipitates on the junction are likely to form.Glass Electrode Body
The glass electrode body is suitable for a wide range of applications due to its chemical resistance. The glass electrode is compatible with many non-aqueous solvents and other aggressive chemicals. Glass is also resistant to many forms of radiation, such as ultraviolet radiation.Features at-a-glance:
- Digital, microprocessor based - no high impedance signal to the meter
- Built-in temperature sensor - no need for an additional temperature probe
- 3.5mm digital plug - easy to plug in, no alignment necessary
- Double junction reference – eliminates silver precipitates and clogged junctions
- CPS sleeve junction- Clogging Prevention System sleeve junction resists clogging from solid particles typical in wine must, providing longer electrode life than conventional ceramic reference junctions.
- General purpose (GP) glass - allows optimal measurements in ambient conditions
