Digital pH PEEK electrode SenTix® Top 940 | low-maintenance | with temperature sensor

The SenTix® Top 940 electrode is developed for a wide range of applications in the laboratory, field and process from wastewater to emulsions, solutions with proteins, suspensions to purely aqueous samples. This is achieved through the special mechanical and chemical resistance of the PEEK shaft as well as the process-proven components of the measuring and reference electrode.

The reference electrode has a double junction system with a small outer hole and an inner labyrinth-like reference element. With this design clogging of the diaphragm and poisoning of the reference system are made considerably more difficult by. The saturation with finely dispersed KCl of the solid Duralid® reference electrolyte is another reason for the long zero-point stability and the associated long operation life of the SenTix® Top 940 electrodes. The small hole furthermore reduces the loss of KCl through bleeding, for example, and allows a fast response time.

Digital SenTix® pH electrodes have a built-in temperature sensor, are QSC-capable, have a memory for 10 calibrations and a stored serial number. The measured values are reliable thanks to the signal processing in the sensor and changing electrodes is easy thanks to the calibration data stored in the sensor.

The SenTix® Top 940 is particularly suitable for the following applications:
