In-situ soil pH probe

Permanent in-situ measurement of the soil pH in laboratory and field applications, frost resistant, durable, low maintenance.

Principles of operation

The pH glass probe for soils works in combination with a separated reference electrode (Ag/AgCl) as a two probe electrode. It is therefore protected against accelerated aging due to losses of electrolyte solution via a diaphragm. The leakage of the electrolyte is prevented by imbedding the reference electrode in a so-called salt bridge with thickened KCl which has got the electrical contact to the soil. It is applicable together with ecoTech's redox electrode with the same special designed monitoring module and even in combination with the redox electrode in the same circuit.
