Reference Electrode External Salt Bridge, L-Shaped Lugin Capillary, Sand core Salt Bridge Reference Electrode External Salt Bridge

Reference electrode external salt bridge , L-shaped Lugin capillary, sand core salt bridge Reference electrode external salt bridgeClassification.A: External salt bridge with double salt bridge reference electrodeB: L-shaped Lugin capillaryC: L-shaped ceramic sand-core salt bridgeD: Straight ceramic sand-core salt bridgeNature: When there is a current through the measuring cell, thethere is an ohmic potential drop in the solution between the two electrodes.It is more pronounced for solutions with higher resistivity and higher currents.To reduce its effect on the potential measurementthe glass tube at the solution end of the reference electrode is drawn into a capillary tube, the Lugin capillaryand make it as close to the working electrode as possible.so that almost no current passes through the measurement circuit of the reference electrode.In this way a high resistance voltmeter can be used to obtain more accurate potential data.The function of the Lugin capillary is to eliminate the resistive superpotential.The three electrodes (electrode to be measured, auxiliary electrode, reference electrode), thethe auxiliary electrode and the electrode to be measured, change the resistance in the circuit, thecontrol of the current density of the electrode to be measured to obtain different superpotentials.The reference electrode and the electrode to be measured are used to determine the potential of the electrode to be measured by the pair elimination method.Packing: 1PCWarranty period: 120 days
