The Sensor Chip in the electrode head stores data such as sensor type, serial number, calibration data, and usable life, which is automatically read out to the titrator setup when connected. That ensures, without any action on the part of the operator, that only the correct sensor with the specific, valid data is used.
Alongside experienced craftsmanship, the maximum utility of automated production methods ensures the consistently high quality expected of the sensors.
No sensor leaves the production facility untested. Only on successful completion of the final check do the sensors receive their individual quality certificates ready for dispatch. Strict guidelines regarding the slope or membrane glass resistance of the pH sensors guarantee ultimate performance.

In Karl Fischer water determinations, a polarized platinum double-pin electrode is used to detect the presence of water in a sample. The electrode consists of two platinum pins that are constantly polarized with a current (Ipol), while the potential required to maintain this current is monitored. At one of the pins, iodine molecules are reduced to iodide ions, while at the other pin, iodide ions are oxidized back to iodine. This process creates an increased flow of charge carriers, which reduces the required potential. When water is present in the sample, all the iodine molecules are consumed, leading to a higher potential. Therefore, measuring the change in potential can accurately determine the amount of water in the sample.
To ensure optimal performance and longevity, regular maintenance is crucial. Here are some general key points for properly maintaining a titration sensor:
