產品描述：參考電極為Ag/AgCl電極。它作為氧化還原(鉑)電極電位差的參考點。它由一個銀絲用AgCl封好，放入3 M溶液中氯化鉀。電解液的電接觸是由周圍的土壤通過陶瓷隔膜提供的。

英文描述：The reference electrode is an Ag/AgCl electrode. It functions as reference point for the potentials difference to the redox-(Platinum-)electrode. It consists of a silver wire which is sealed with AgCl and plunged into a 3 M solution of potassium chloride. The electrical contact of the electrolyte solution to the surrounding soil is given by a ceramic diaphragm.
