Flexible Connection of pH Electrodes and ORP Probes

Any pH or ORP electrode can now be fitted to instruments from the company Ahlborn (Germany), using a cable with a programmable ALMEMO connector with a built in transducer. For example, all conventional electrodes with a plug head S7/SN6 can be connected. So as not to distort the measurement signal through the meter, an extremely high-impedance amplifier is integrated in to the cable plug. With this Impedance transformation multiple electrodes with different potentials can be measured through just 1 instrument. For probes with a SMEK type plug head a special cable is available with a transducer built in to the ALMEMO connector. Programming of this cable connector is designed for pH probes with an integrated NTC temperature sensor, with the linearisation stored in the plug. Due to the complete isolation of measuring inputs to the meter, it is possible to measure different samples with multiple probes. Via the programmable ALMEMO plug any sensor can be connected.
