Brake Fluid Tester for DOT3 DOT4 DOT5.1

The TROPRO brake fluid tester checks moisture content in DOT3, DOT4 and DOT5.1 brake fluids. It suits private owners and workshops that need a quick health check on hydraulic brake systems. The compact grey handset fits in a glovebox or tool drawer for on-the-spot testing. No vehicle-specific adapters are required.

LCD Readings and Audible Alarm

A high-resolution LCD shows the water-percentage result in seconds, readable in sunlight or darkness. The probe delivers high sensitivity and flexibility for tight bleed nipples. When moisture exceeds the threshold the built-in sounder alerts the user immediately. The probe tip also includes a flashlight to inspect fluid colour.

Limits of the Moisture Scale

The device reports three fixed bands: below 1 % for DOT3 indicates high purity, below 2 % for DOT4 is acceptable, and above 4 % for DOT5.1 signals replacement. It cannot quantify moisture outside these bands or distinguish fluid types beyond DOT3, DOT4 and DOT5.1. Users needing laboratory-grade analysis or data logging must use different equipment.

Questions about this item

Will this tester work with DOT 4 fluid already in my older car?

Yes, the tester supports DOT 3, DOT 4 and DOT 5.1 fluids, so it can check the fluid currently in most vehicles.

How do I know the device is giving a correct reading after I turn it on?

The LCD screen shows the moisture percentage and a description such as High Purity or Need to Replace, and an audible alarm sounds if the water content exceeds the limit.

What comes in the box and do I need to buy anything else to start testing?

The tester itself is supplied; no separate probes or fluids are required, and a built-in flashlight on the probe lets you inspect fluid colour.
