The invention provides a tester of penetrating type devices. The tester comprises a pedestal, at least three probes are laid on the pedestal along a first direction, each probe is provided with a conductive pole which extends along the first direction, the conductive pole includes a conductive end which extends into a corresponding hole of the penetrating type device and is connected with the corresponding conductive pole of the adjacent probe, and two adjacent probes can move relatively along the first direction to form a test position. At least three probes are laid along the first direction, every two adjacent probes can move relatively along the first direction, the three probes form at least two test positions, during test, the penetrating type devices are placed in the test positions, holes of the penetrating type devices correspond to the conductive poles of the probes, the conductive ends of the corresponding conductive poles move relatively and are connected, a current penetrates the holes, and test is completed. The tester can test multiple penetrating devices synchronously via once clamping, and the test efficiency is high.
