The device heats a fluid sample via the integrated probe and continuously records the temperature until the boiling point is reached. Because moisture in brake fluid directly lowers the boiling point — increasing the risk of vapor lock during intensive braking — this measurement method provides the most reliable indication of the fluid’s actual condition.\u003c\/p\u003e\n\u003cp\u003eThe AS506 has two test modes. In \u003cstrong\u003enormal mode\u003c\/strong\u003e, the device tests nine fluid types: \u003cstrong\u003eDOT 3, DOT 4, DOT 4+, DOT 4 ESP, DOT 5, DOT 5.1, DOT 5.1 ESP, ENV4, and ENV6\u003c\/strong\u003e. In \u003cstrong\u003ebrand mode\u003c\/strong\u003e, the device directly compares the measurement with factory values of fourteen brake fluid brands, including ATE, TRW, Bosch, Motul, Brembo, Textar, and Ferodo. The result appears within about 16 seconds on the illuminated LCD screen, along with the official dry and wet boiling point values for reference.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display: flex;
