Easy to replace, providing hydrogen gas for the electrode. The hydrogen electrode has no internal electrolyte, therefore there is no ion outlet and no diffusion potential. No need for electrolyte replenishment The hydrogen electrode does not contain toxic heavy metals. Can be used for fluorine-containing concentrated media as it is made of PTFE. Very effective in high concentration alkaline and acidic media (pH-2 to pH16)
