The next generation: Electronic brake fluid tester

Digital, precise & workshop-ready

The Leitenberger EBT 03.3 brake fluid tester is a professional, digital measuring device for the quick and reliable testing of brake fluid in automotive workshops. It enables the precise determination of the water content (%) and boiling point (°C) and also provides a clear recommendation as to whether the brake fluid should be changed. The EBT 03.3 is based on 57 years of experience, extensive laboratory analyses, and numerous brake fluid test series. It is the logical next step in the development of the proven EBT 03 and EBT 03 USB models.

Precise, state-of-the-art measurement technology

The EBT 03.3 brake fluid tester uses the same robust sensor, proven over 10,000 times, as its predecessors. However, the electronics and software have been completely modernized and updated to the latest technological standards.

Your advantages:

• high measuring accuracy
• very good repeatability
• Current brake fluid types stored
• fast measurement results directly on the vehicle

Check brake fluid – quickly & reliably

With the EBT 03.3 brake fluid tester you can measure:

• Water content of brake fluid in %
• Boiling point of brake fluid in °C
• Change recommendation: Brake fluid change – Yes / No

Ideal for safe vehicle diagnostics, transparent customer advice and documented workshop processes.

Suitable for all common brake fluids (glycol-based)

The electronic brake fluid tester is suitable for:

• DOT 3
• DOT 4
• DOT 4 Plus
• DOT 5.1
• DOT 4 Class 4 (ISO 4925 – Class 4)
• DOT 4 Class 6 (ISO 4925 – Class 6)

Stand-alone or with digital documentation

The EBT 03.3 can:

• can be used as a stand-alone measuring device (display directly on the screen)
• or connected to a PC via USB interface for digital documentation

The software allows you to:

• Measurement results (water content & boiling point)
• Switching recommendations

Store, manage and assign to vehicles and customers – ideal for test reports and proofs.

Measuring ranges

• Boiling point: 130 °C to 300 °C (1 °C increments)
• Water content: 0.1% to 10.0% (0.1% increments)

Self-assessment & Safety

The brake fluid tester features:

• Self-test function
• Water detection (simulation of a measurement error)

The EBT checker is required for complete self-testing (not included).

Legally compliant (Austria)

The brake fluid tester EBT 03.3 meets the requirements according to Annex 2a Z 16 PBStV for the periodic inspection of motor vehicles according to § 57a KFG 1967 (Austria).

Note on measurement technology

All brake fluid testers – including the EBT 03.3 – use indirect measurement methods. Functionality can be tested across the entire measuring range, however, the creation of calibration certificates is not possible.

Scope of delivery

• Electronic brake fluid tester EBT 03.3
• USB cable (USB-A to USB-C, 1.2 m)
• Software for creating test reports (download)
• User manuals (device & software)
• Sturdy transport case
