Summary
This instrument is primarily used to test the rust prevention performance of brake fluid.
The principle involves placing the brake fluid into the device, setting the temperature to 35°C, and maintaining a humidity level of 91% for a period of 24 hours. The rust prevention capability of the brake fluid is then assessed based on the condition of the test specimen's surface.
