ISO4925 Rust Prevention Performance Test Apparatus for Brake Fluid

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.
