During detection, the lower end of the detection sample 4 is inserted into the test liquid in the conductive container 2. The detection sample 4 is powered by the tester 1, and timing is performed. After power supply for a specified time, the capacitance is read, and then the oxidation film thickness of the aluminum foil can be calculated through a formula. The detection sample 4 is clamped by the cooperation of the heterogeneous clamping piece 7 and the clamping portion 8. The detection sample 4 does not need to be held by a detection operator for detection, which is convenient to operate. The detection sample 4 maintains a stable clamping state during the whole detection process, so that the detection area is not fixed due to hand shaking of the detection operator, and the detection data is not accurate.

By setting the clamping part 8 and the female clamping piece 7 in the shape of an inverted "F", the female clamping piece 7 and the clamping part 8 both include two clamping arms arranged in parallel with each other. The clamping structure can adopt a bolt and a nut. A plurality of connecting holes are arranged on the female clamping piece 7 and the clamping part 8 in correspondence. The clamping arms of the clamping part 8 and the female clamping piece 7 are both provided with clamping planes. After the upper end of the detection sample 4 is attached to the clamping planes of the two clamping arms of the clamping part 8, the clamping planes of the two clamping arms of the female clamping piece 7 are attached to the other side surface of the detection sample 4.
