Dedicated pH-ORP electrode for the HI2000edge tablet series

• HI11310 is a glass-body refillable double-junction pH electrode with a built-in temperature sensor, enabling temperature-compensated measurement in a single-probe design. The probe connects to the meter via 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 has a single ceramic junction, and the spherical pH sensing portion is made of high-temperature glass. This design consideration makes it ideal for general laboratory use.

• Built-in microchip

• The built-in microchip stores sensor type, serial number and calibration information, including date, time, offset, slope, probe condition and the buffers used. Upon inserting the electrode, the edge® automatically retrieves this information. The ability to transfer information allows hot-swapping of probes without recalibration.   All pH measurements are performed within the electrode and transmitted digitally to the meter. This overcomes any noise issues associated with traditional high-impedance analog measurement systems. Built-in temperature sensor and electrical noise generated when working in humid environments.

Figure 2 details:

• Spherical glass tip

• The spherical tip design allows a large contact area with the sample. This allows for faster electrode response and higher stability. The HI11310 uses a high-temperature (HT) glass formulation. A pH electrode with general purpose (GP) glass has a resistance of 100 megohms at 25°C, while HT glass has a resistance of approximately 400 megohms at 25°C.  When the HI11310 is used at high temperatures, the resistance decreases to close to that of GP glass. The HI11310 is suitable for samples with a measurement range of -5 to 100°C.

Figure 3 details:

• Double-junction reference

• A double-junction electrode has an internal compartment around 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 almost no silver from the electrode enters the sample. This design allows measurements in applications where silver ions are not desired in the sample or where silver precipitates may form at the junction.

Figure 4 details:

• Glass electrode body

• The glass electrode body is suitable for a wide range of applications due to its chemical resistance. Glass electrodes are compatible with many non-aqueous solvents and other corrosive chemicals. Glass also resists many forms of radiation, such as ultraviolet radiation.

Figure 5 details:

• Built-in temperature sensor

• The HI11310 features a built-in thermistor temperature sensor located at the tip of the indicating pH electrode. The thermistor temperature sensor provides high-accuracy temperature readings and should be as close as possible to the indicating pH electrode to compensate for the effect of temperature on the membrane potential. By obtaining accurate readings, accurate temperature-compensated readings can be provided.
