Wet film thickness testing seal

The utility model relates to the technical field of humidity film thickness testing, in particular to a wet film thickness testing seal, which comprises a testing substrate for spraying a testing coating to form a to-be-tested wet film; the seal body is fixedly provided with a plurality of seal test probes, the plurality of seal test probes are arranged at equal intervals, and when the seal body covers the test substrate, the seal test probes penetrate through a to-be-tested wet film and then are in contact with the test substrate. The method has the effects of reducing the measurement error value of the wet film and improving the test accuracy. 本申请涉及湿度模厚度测试技术领域，尤其是涉及一种湿膜厚度测试印章，其包括：测试基板，供测试涂料喷涂形成待测湿膜；印章本体，固定设有印章测针，所述印章测针设置有多个，多个所述印章测针之间等距间隔布置，所述印章本体盖合于所述测试基板上时，所述印章测针穿过待测湿膜后与所述测试基板接触。本申请具有减少湿膜的测量误差值，提高测试准确性的效果。
