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.

Analog pH electrodes for food measurement

The SenTix® Rx-T 900 digital ORP electrode with its plastic shaft is suitable for mobile field measurements and is low-maintenance thanks to its gel filling. The SenTix® Rx-T 900 has an easy-to-handle fiber diaphragm and a platinum pin membrane (1 mm). All redox electrodes consist of a metal electrode made of a precious metal and a reference electrode. As with all SenTix® electrodes, the reference system is silver/silver chloride. 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 electrode replacement is easy thanks to the calibration data stored in the sensor.

The SenTix® 81-87 pH electrodes with their high-quality glass shaft and refillable 3 mol/l KCl liquid electrolyte and platinum diaphragm are suitable for demanding measurements in the laboratory. The platinum wire diaphragm offers optimum electrolyte flow without clogging and the liquid electrolyte offers fast response times. The electrodes can also be used in difficult samples. The cone shape of the membrane is impact-resistant and easy to clean. These electrodes have different temperature sensors (see table “Connections & variants”).

The Sentix® 41-47 pH electrodes with their plastic shaft are particularly suitable for mobile (field) pH measurement. The cylindrical shape of the membrane is robust and the fiber diaphragm prevents clogging. With the gel electrolyte filling, these electrodes are low-maintenance and do not need to be refilled.

The SenTix® ORP and Ag redox electrodes with their glass shaft made of high-quality membrane glass and the ceramic diaphragm are suitable for demanding measurements in the laboratory. All redox/ORP electrodes consist of a metal electrode made of a precious metal and a reference electrode. As with all SenTix® electrodes, the reference system is silver/silver chloride.

Robust and flexible IDS pH measurement

IDS ORP measurement for general applications

IDS pH measurement in small volumes

The SenTix® 51-57 pH electrodes with their plastic shaft are suitable for mobile (field) pH measurement as well as for pH measurement in the laboratory in water and aqueous solutions. The cylindrical shape of the membrane and the ceramic diaphragm are robust. These electrodes are refillable and respond quickly due to the liquid electrolyte and have various temperature sensors (see table “Connections & variants”).

The SenTix® 60-62 pH electrodes with their high-quality glass shaft, refillable 3 mol/l KCl liquid electrolyte and platinum diaphragm are suitable for demanding measurements in the laboratory. The platinum wire diaphragm offers optimum electrolyte flow without clogging and the liquid electrolyte offers fast response times. The electrodes can also be used in difficult samples. The cone shape of the membrane is shock-resistant and easy to clean. Temperature compensation is carried out either manually or via an external temperature sensor.

The SenTix® Rx ORP electrode with its plastic shaft is suitable for mobile field measurements. The SenTix® Rx electrode is low-maintenance thanks to the gel filling and has an easy-to-use fiber diaphragm and a platinum pin membrane (1 mm). All redox electrodes consist of a metal electrode made of a precious metal and a reference electrode. As with all SenTix® electrodes, the reference system is silver/silver chloride.

The SenTix® 91 pH electrode has a length of 170 mm and, with its high-quality glass shaft, refillable 3 mol/l KCl liquid electrolyte and platinum diaphragm, is suitable for demanding measurements in the laboratory. The platinum wire diaphragm offers optimum electrolyte flow without clogging and the liquid electrolyte offers fast response times. The electrode can also be used in difficult samples. The spherical shape of the diaphragm offers constant measurement quality and low resistance due to the large surface area. This electrode has an NTC 30 kOhm temperature sensor.
