Two sides of test cellconnect to both electrode (the anode and cathode), with the middle being connected to the reference electrode which can be used for monitoring voltage variations of the two electrodes.
TOB-3ESTC15P Three-Electrode Split Test Cell with Pressure Gauge is used for R&D Battery - 15 mm Diameter Cell , to reference electrode between the anode and the cathode.
TOB-SL3Ex-series three electrode battery test cell included 3 models: TOB-SL3E1-12, TOB-SL3E2-14, TOB-SL3E3-16, Please contact us for more information.
