Product Details
✓Measure Actual Boiling Point: AS506 heats a collected brake fluid sample and measures its boiling temperature. It delivers a temperature result rather than the moisture estimate provided by conductivity-style tester pens.
✓Fast 16-Second OLED Workflow: Connect to a 12V vehicle battery, choose Normal or Brand Mode, immerse the sampling hole and hold Start. The OLED shows voltage, live temperature, progress and measured result; dry and wet values are references.
✓Wide Brake Fluid Coverage: Supports DOT 3, DOT 4, DOT 4+, DOT 4 ESP, DOT 5, DOT 5.1, DOT 5.1 ESP, ENV4 and ENV6. Brand Mode includes 14 built-in reference profiles for commonly used brake fluid brands.
✓Workshop-Ready Test Kit: Includes the AS506 tester, 50 ml sampler, matching hose and 50 ml beaker. Reverse-polarity protection helps reduce connection risk, while Celsius and Fahrenheit display supports different service workflows.
✓Confirm Before Ordering: Not an in-reservoir pen. Each test needs 40-50 ml of brake fluid and 12V battery power. The sample and probe become hot, tested fluid cannot be returned to the reservoir, and repeat tests require a fresh sample.
