Technical parameters: Green: Battery OK, that is, brake fluid does not contain water Green / yellow: brake oil in water content of less than 1%, better brake fluid performance, ease of use. Green / yellow / yellow: brake oil in water content of about 2%, brake fluid can continue to use. Green / yellow / yellow / red: brake oil in water content of about 3%, the proposed replacement of brake fluid. Green / yellow / yellow / red / red: brake oil in water content of at least 4%, the brake fluid must be replaced immediately responsible for very dangerous.

• Quickly determine percentage of moisture in brake fluid Measurement range: 0% - 4% Power supply: 1.5V "AAA" x 1 (not included) 5 LEDs indicating the water % in the brake fluid
• CE and RoHS Approved Calibrated for DOT 4 fluid only Compact, at only 6" Length Principle: according to conductivity changes to determine moisture change in brake fluid, with five different color LED indicator
• The tester can be used as a digital brake fluid tester suitable for determining brake fluid quality.Developed for professional use in astomotive repair shops and in servicing.Quality is tested and included on five LEDs in terms of "per cent of water in the brake fluid".
• Ready for Brake Fluid Test Unscrew the brake fluid reservoir,and pull off the cap of the Brake fluid tester.Dip the test probes into the brake fluid up to the plastic rim of the device.
• To check Fluid Quality Press the button for power on,green LED will light up.Insert the tester into reservoir for one second then the tester result will be correctly indicated by LEDs.Repress the button for power off.The tester will automatically power off after about 15 seconds of inactivity.
