ITEQ Brake Fluid Tester Pen with 5 LEDs — Calibrated for DOT3 & DOT4

Fast, visual brake fluid testing in your garage

The ITEQ Brake Fluid Tester Pen gives you a quick, visual read on the water content in DOT3 or DOT4 brake fluid. Its compact form fits in a glove box or tool drawer, while the five LED indicators translate fluid condition into an easy-to-read color signal. This helps you spot when a fluid change might be worth considering, whether you’re prepping for a trip or after topping up the reservoir.

How it works

Power the device with a single press. The tester samples the brake fluid through its probes and lights up a color sequence that reflects moisture levels. If the battery needs attention, a prompt will help you decide when to replace it. After testing, reattach the reservoir cap to keep the area clean, and note that the tester automatically powers off after about 12 seconds of inactivity.

• Green means no detectable water
• Green/Yellow indicates less than 1% water
• Green/Yellow/Yellow corresponds to around 2% water
• Green/Yellow/Yellow/Red signals roughly 3% water, suggesting a fluid change may be needed
• Green/Yellow/Yellow/Red/Red indicates about 4% water, an urgent change could be warranted
