AUTOOL AS507 · Power Steering Fluid Tester
Reach and Screen Power Steering Fluid
Screen power-steering fluid transparency and temperature from the reservoir. AS507 uses a flexible PTFE probe to reach the fluid, then presents transmittance, temperature, and status guidance together on a backlit display. Battery power keeps the handheld check independent of the vehicle’s electrical supply.

Key Features
Optical Power Steering Fluid Screening Through a 350mm Probe
High-Precision Optical Probe
Integrated with a high-precision optoelectronic sensor to support more accurate power steering fluid measurement.
Oil Temperature Display
Built-in temperature sensor helps evaluate power steering system working condition and supports °C / °F display.
350mm Flexible PTFE Hose Probe
The 350mm probe reaches the reservoir more easily. PTFE hose material resists oil, oxidation, and corrosion.
Clear Display Status
The screen shows battery level, transmittance, temperature, backlight, sound, OK, warning, and suggested replacement status.
User-Friendly Handheld Design
Silicone-lined grip and lightweight body make single-handed testing easier in workshop conditions.
2.8-inch Backlit LCD
Large backlit display improves readability under different lighting conditions and supports quick test-result review.
AAA Battery Operation
The 175 × 72 × 29mm tester uses four AAA batteries for 6V operation.
Power Steering Fluid Testing
AS507 evaluates power steering fluid through transmittance measurement and temperature display.

Buyer Questions
Fluid Fit, Method and Result Questions
What Does AUTOOL AS507 Test?
AS507 tests power steering fluid condition by evaluating transmittance and impurity level. It is designed to help users judge whether power steering fluid is in good condition, needs attention, or should be replaced.
How Does AS507 Judge The Fluid Condition?
AS507 uses a high-precision optical probe and big data algorithm analysis to evaluate fluid transmittance and impurity level. The screen shows transmittance, temperature, and status guidance such as OK, warning, or suggested replacement.
Can AS507 Display Oil Temperature?
Yes. AS507 includes a temperature sensor and can display temperature in °C or °F. The temperature measurement range is 0-85°C / 0-185°F.
How Long Is The Probe?
The flexible probe is 350mm long. The test cable length is 80cm, and the hose uses Teflon / PTFE material for oil resistance, oxidation resistance, and corrosion resistance.
What Batteries Does AS507 Use?
AS507 uses 4 AAA batteries and operates at 6V. Replace the batteries when the battery level is low.
How Do I Use AS507?
Wipe the probe, insert it into the power steering fluid, press the test button, and read the result on the display. Clean the probe before and after testing to avoid contamination.
Can AS507 Test Brake Fluid, Engine Oil, Or Transmission Fluid?
AS507 is designed for power steering fluid testing. For other fluids, choose the matching AS series tester: AS502 for brake fluid water content, AS503 for engine oil quality, AS505 for transmission fluid, or AS506 for brake fluid boiling point.
What Is The Difference Between AS507 And Other AUTOOL Fluid Testers?
AS507 focuses on power steering fluid transmittance and impurity evaluation. AS502 tests brake fluid water content, AS503 tests engine oil quality, AS505 tests transmission fluid, and AS506 tests brake fluid boiling point. Choose the tester according to the fluid type first.
How Long Is The Warranty?
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
