SUP-PH6.0 Online pH meter is a multivariable analyzer used for measuring/controlling the pH and ORP with different temperature. The function is switchable on the device itself. Depending on the measured variable, combination electrodes (e. g. pH sensors) or split versions (glass electrodes with a separate reference electrode) can be readily connected.
