pH electrodes are the most commonly used electrochemical sensors. At the same time, they provide the most sensitive measuring signals and must be serviced and calibrated on a routine basis. The concept of IDS sensors precisely takes effect here.
Digital data transfer without interferences allows the user to use a long cable and enables important additional information such as calibration data and sensor ID.

SenTix® 945

A pH electrode with glass shaft, gel reference and 3 ceramic junctions, suited for precise laboratory measurements with quick response combined with low maintenance. It provides reliable measurements even in difficult samples and has a built-in temperature sensor.

SenTix® Micro 900

A micro pH electrode filled with 3 mol/l KCl and extra-long in diameter reduced shaft. It is suitable for pH measurement of small volumes or in small vessels particularly in applications of pharmaceutical, Life Science or bio technology labs. The electrode has a built-in temperature sensor.

SenTix® Sp-T 900

Spear type electrode with built-in temperature sensors for measurement of semi-solid samples like meat, cheese, fruit and many more. With hole junction and polymer electrolyte, insensitive against clogging and easy to clean.

SenTix® HW-T 900

A special pH electrode including a built-in temperature sensor, filled with 3 mol/l KCL for measurement of samples with either low or high ion concentration, but also for emulsions and suspensions. This is provided by an adjustable electrolyte flow with a special split ring junction.
