Ion selective electrodes are sensitive to the concentration of a specific ion present in the sample and are variable potential electrodes. They are used in conjunction with a reference electrode to measure the concentration of the ions. The wide range of electrodes offered by HORIBA is the result of many years of experience, development and research in electrochemical technology.
When making measurements with an ion meter, calibration with various standard solutions allows for direct measurement of the desired ion concentration. Note that since ion analyses are affected by temperature, values must be measured at a fixed temperature, or an additional temperature electrode must be used to utilize the temperature compensation function.

*1 The allowable pH range for the measured ion concentration at the value in parentheses (pH range varies slightly depending on the ion concentration).
*2 The change in electrode potential when the ion concentration becomes 10 times higher (at 25°C)
*3 The allowable coexistence limit value is the ratio of the limit concentration (mol/L) of the coexisting ion species to the measurement target ion concentration (mol/L).
For example, in the case of 1000, the measured value is not affected if the coexisting ion concentration is up to 1000 times the measured ion concentration. "
Not possible" means that measurement is not possible due to the ion electrode's response membrane being altered by a chemical reaction.
