Summary
This Rust Prevention Performance Measuring Apparatus 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.
Main features
◆ The glass test tube meets standard requirements, with a diameter of 22mm and a height of 175mm;
◆ The heating chamber is equipped with ventilation holes on the top;
◆ Comes with cast iron pieces, measuring 80mm in length, 13mm in width, and 2.5mm in thickness, as well as aluminum pieces of the same dimensions;
◆ Comes with aluminum foil with a thickness ranging from 0.02 to 0.06mm, containing 99.9% tin;
◆ The microcomputer temperature controller features PID self-tuning and a PT100 temperature sensor for high precision;
◆ The digital time controller has a buzzer alarm to indicate the end of the test;
◆ The instrument's casing is made of cold-rolled steel and treated with electrostatic spray coating.
