AUTOOL AS506 Automobile Brake Fluid Tester

The AUTOOL AS506 is a handheld automotive brake fluid tester designed to help judge whether brake fluid should be replaced by checking boiling point performance. It supports DOT 3, DOT 4, DOT4+, DOT4ESP, DOT 5, DOT 5.1, DOT5.1ESP, ENV4, and ENV6 brake fluids, provides Normal Mode and Brand Mode, and delivers a test result in about 16 seconds. AS506 heats brake fluid during the boiling point test. Review the sample volume, 12V power rule, hot-fluid warning, and post-test handling instructions before use. AS506 focuses on boiling point detection for brake fluid maintenance decisions, with dual test modes, fast detection, clear OLED prompts, wide brake fluid coverage, and reverse polarity protection. AS506 supports 9 brake fluid types and two test modes, so users can test by general brake fluid type or by built-in brand reference when applicable. Use the injection sampler to collect brake fluid, connect AS506 to a 12V battery, select the proper mode and fluid type, then press and hold the S button for about 16 seconds to complete the test.
