Product Overview

HI763100 is a digital conductivity electrode with a built-in temperature sensor. Compared with the electrochemical design of other conductivity probes, the HI763100 is a potentiometric probe with a platinum sensor, allowing measurement of high or low conductivity ranges with a single probe. The electrode has an integrated microchip that stores calibration data, electrode type, and serial number. The HI763100 is designed for use with Hanna's edge® pH/EC/DO meters.

Figure 1 details:

• 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. When the electrode is inserted, the edge® automatically retrieves this information. The ability to transfer information allows hot-swappable probes without recalibration. All pH measurements are performed inside the electrode and transmitted digitally to the meter. This overcomes any noise issues associated with conventional high-impedance analog measurement systems. When working in humid environments, the built-in temperature sensor may generate electrical noise.

Figure 2 details:

• Potentiometric measurement system

• The four-ring potentiometric measurement system allows measurement of a wide range of samples while minimizing the effects of polarization. The two outer rings apply an AC voltage and induce a current loop in the solution, while the two inner rings measure the voltage drop induced by the current loop. This allows a range from very high to very low readings without changing the electrode.

Figure 3 details:

• Sleeve

• A chemically resistant plastic sleeve surrounds the probe to control external interference from the sample. It also allows the current loop to be generated in a controlled area.

Figure 4 details:

• Internal temperature sensor

• Since temperature is an important factor in conductivity measurement, having a built-in temperature sensor on the probe is very helpful. No external temperature probe is needed, making measurement easy. The coefficient used to correct for temperature changes is β, expressed as a percentage of the reading per degree Celsius.
