METEMIS mini-ISE are miniature specific electrodes. While the standard size for ISE is around 10 cm, mini-ISE are millimeter sized sensors.
Its small size allows to get pocket size multiparametric probes, and to reduce chemical interferences which increase the measurement quality. They are low power and so ultra-mobile.
In addition of the 50 time reduced size, the membrane of the sensor is mechanically resistant (several bars pressure), handles vibrations and falls (in opposite of glass probes). In some cases, it is biocompatible according ISO 13985 and sterilisable.
They allows to measure in liquid media a large range of molecules and ions such as sodium, pH, potassium, phosphate or calcium. But METEMIS has more than 15 ions in its catalog and can develop other on demand.
