Ag/AgCl - reference electrode

 

The Ag/AgCl - reference electrode is an electrode with a defined and stable potential. It consists of a silver wire coated with silver chloride immersed in a 3 M KCl-filling solution (single bridge). The electrode is surrounded of a second electrolytic solution (double bridge) to avoid interfer-ence of the measuring solution by escaping silver and chloride ions of the filling solution.

 

Following filling solutions are suitable for the double bridge:
1 M KNO3- – solution for the measurement of Ag+, Cl-, Br-, I-, CN-
1 M Na2SO4 – solution for the measurement of NO3-

 

Applications:
Reference electrode for all ion-selective electrodes

Soil probe

The stainless steel soil probe is a tool used for detecting (or probing) soil layer densities, water permeability levels, and soil types. It does not require the soil to be dug up. It can be used to detect zones within the topsoil layer... ...more Topseller
