AMT – pH sensor

The pH Sensor uses a pressure-balanced glass electrode with a built-in reference to provide in-situ measurements up to 1200m depth. The sensor is equipped with a reference system using a solid gel (stiff polymer mass containing Ag+-free KCl) and a ceramic pore diaphragm. The pH probe is permanently sealed and supplied with a soaker bottle attachment. The bottle contents must always contain a storage solution when the probe is out of use. The storage solution should be a 3m KCl solution with a buffered pH value of approximately 3,5…4, that prevents the reference electrode from drying out during storage.
This sensor is absolutely H2S resistant due to the silver-free reference electrolyte.
