Digital Glass Body pH Electrode for General Purpose – IC-HI11310

The HI11310 is a glass body refillable double junction pH electrode with a built-in temperature sensor for temperature compensated measurements in a single probe design. This probe connects to the meter with a 3.5 mm connector. The 3.5 mm connector is proprietary to meters that use digital electrodes.

The HI11310 electrode features a built-in microchip that stores sensor type, serial number, and calibration information. It also features a single ceramic junction and the spherical pH sensing portion is made with high temperature glass. This design consideration is ideal for general purpose laboratory use.
Features: – 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 low temperature (LT) glass formulation that has a resistance of around 50 mega ohms at 25 C. As the temperature of the glass decreases in the sample, the resistance of the LT glass will approach that of GP glass. If using GP glass, the resistance would increase above the optimum range, resulting in increased impedance and ultimately affecting the measurement. The HI10480 is suitable to use with samples that measure from 0 to 80 C. – 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. – Built-In Temperature Sensor: HI11310 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. By having an accurate reading it is possible to provide an accurate temperature compensated reading.
