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.
