Brake Fluid Tester Pen – DOT 3, DOT 4 & DOT 5.1 Moisture / Water Content LED Tester

Keep an eye on the condition of your brake fluid with this quick and easy Brake Fluid Tester Pen. Brake fluid absorbs moisture over time, which can reduce braking performance and lower the fluid's boiling point.

Simply switch the tester on and place the two probes into the brake fluid reservoir. The colour-coded LED display gives an instant indication of the approximate moisture level.

Features:

• Tests brake fluid for moisture / water content
• Clear 5-stage LED indication: 0%, 1%, 2%, 3% and >4%
• Quick and simple to use
• Suitable for DOT 3, DOT 4 and DOT 5.1 glycol-based brake fluids
• Compact pen-style design with pocket clip
• Ideal for cars, vans and motorcycles
• Useful for home mechanics and professional workshops
• Easy way to help identify when brake fluid may need replacing
