product description
Why choose thelockerguy wholesale?
The Autool AS502 is a handheld brake fluid tester that directly measures the moisture content in brake fluid inside the reservoir. The device is suitable for brake fluids based on DOT3, DOT4, and DOT5.1 and displays the measurement on an LCD screen with backlight. A flexible measuring probe on the top allows measurements even in hard-to-reach reservoirs.
During use, the probe is held in the brake fluid, after which the tester determines the water content in percentage and visually displays the result via a five-step LED indication from green to red. Operation is via four buttons for on/off, start measurement, unit switch, and lighting. The tester runs on AAA batteries and automatically switches off when inactive to extend battery life.
ADVANTAGES
✔
Flexible gooseneck probe also reaches reservoirs with limited access under engine components.
✔
Immediate color indication from green to red shows the brake fluid condition at a glance without interpreting numbers.
✔
Automatic shut-off prevents unnecessary battery drain if the device is forgotten.
✔
Suitable for multiple DOT types, so one tester is enough for various vehicles in the workshop.
KEY POINTS
✕
Batteries are not included in the package and must be purchased separately before use.
✕
Not suitable for brake fluid based on DOT5 (silicone-based), as it differs in composition.
✕
The measurement provides an indication of moisture content and does not replace laboratory analysis in doubtful cases.
Applications and functionalities
The Autool AS502 supports the following measurement and operation functions:
- Brake fluid moisture measurement: Determines the water content in brake fluid and displays the percentage on the screen, allowing the mechanic to assess if replacement is needed.
- LED status display: Five LEDs indicate condition with colors from green through yellow to red for quick visual assessment.
- Unit switching: Switches between display units via a separate button, so the result is shown in the desired notation.
- Backlighting: Illuminates the LCD screen during measurements in dark engine compartments or under workshop lights.
- Automatic shut-off: Turns off the device when inactive, extending battery life.
Package Contents
- 1x Autool AS502 | Brake fluid tester
- 1x Manual

💡
Good to know: Clean the measuring probe after each measurement with a clean, dry cloth. Residues of old brake fluid on the probe can affect the next measurement and result in inaccurate readings.
