The utility model relates to a portable reference electrode tests support, including the box, has offered at the box center and be used for placing reference electrode, run through the electrode channels of box about and, offer on the electrode channels inner wall of electrode channels side with the box in a plurality of apopores of having a perfect understanding, be covered with out the water drum in the box of each apopore side, be provided with the piston in going out the water drum, be provided with one on the piston and stretch into electrode channels's connector by the apopore, be provided with the holding piece for centre gripping reference electrode in connector the inner, go out set up on the water drum one with go out the inlet opening that link up in water drum inner tube chamber. This application simple structure does not need the staff to support, and two people can accomplish test task in 25 minutes to can wash the reference electrode bottom after the test is accomplished, reduce the pollution probability of soil to copper sulphate solution, prolong reference electrode's life.
