This invention belongs to the field of developer testing technology, specifically relating to an automatic developer testing device and method. The automatic developer testing device includes a test developer tank, a rinsing tank, and a standard developer tank, all mounted on a worktable. The worktable is also equipped with a mechanical gripper and a moving mechanism. The test piece has a testing section and a standard section. The mechanical gripper holds the test piece and, with the aid of the moving mechanism, has the freedom to move back and forth between the test developer tank, the rinsing tank, and the standard developer tank. This invention integrates the testing section and the standard section on the test piece, allowing the same test piece to undergo sequential treatment with two different developers within a short time. This ensures that the environmental parameters, such as temperature, are essentially the same during the immersion process of the standard test piece and the test piece. Furthermore, comparison can be completed without replacing the test piece, reducing testing errors caused by individual differences in test pieces and facilitating subsequent comparative observation by staff.
