About this item

QPKING AS507 is an optical power steering fluid condition tester designed for hydraulic power steering systems with an accessible fluid reservoir. It measures changes in fluid transmittance and displays fluid temperature, providing mechanics, repair shops, fleet maintenance teams, and DIY vehicle owners with an additional reference when evaluating fluid condition and planning maintenance. The tester uses a photoelectric sensing probe to check optical changes associated with impurities, contamination, and fluid aging. Results are shown on a clear 2.8-inch backlit LCD, including transmittance, temperature, battery information, and condition indication. The 13.8-inch flexible PTFE probe helps reach narrow or recessed power steering reservoirs while resisting oil, oxidation, and corrosion. To perform a check, clean and dry the probe, open the accessible power steering fluid reservoir with the engine off and cooled, fully immerse the sensing tip, start the test, and review the displayed result. Clean the probe again after use. For more consistent comparisons, use fresh fluid of the same manufacturer specification as a reference when possible. Different power steering fluid colors and formulations can produce different optical readings. Interpret the result together with the vehicle service history, operating symptoms, owner’s manual, and professional inspection. This tester provides a maintenance reference and is not a laboratory chemical analyzer. Compatibility note: AS507 is intended for hydraulic power steering systems that use fluid and have an accessible reservoir. It is not a power steering pressure tester and is not designed for electric power steering systems without fluid. Do not use it for brake fluid, engine oil, transmission fluid, coolant, fuel, or other liquids. The tester requires four AAA batteries.
