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.
