Reference electrode system

摘要

A reference electrode which has an electrolyte solution in a chamber and a reference electrode immersed in said electrolyte solution and has a hydrophobic membrane for generating the diffusion potential between the electrolyte solution and the test solution. Said hydrophobic membrane is composed of organic polymers, preferably of PTFE, and since it has a water entrance pressure of at least 0.03 bar, it does not normally allow water through. <IMAGE>
