AS508 Automotive Fluid Tester

Product Features Five-in-One Fluid Testing One device covers five major fluid testing modules: power steering fluid, brake fluid, lubricating oil, drivetrain fluid, and EV reduction gear oil, meeting routine maintenance and inspection needs for passenger vehicles, commercial vehicles, and new energy vehicles (NEVs). 10-Second Rapid Testing After the optical sensor is immersed in the fluid being tested, the test result is displayed in approximately 10 seconds. No waiting or heating is required, and the test can be performed without disassembly or draining the fluid. Automatic Result Classification Test results are automatically classified into three levels: Good / Fair / Poor. For brake fluid, the classification is based on water content: <2% — Good; 2%–3% — Fair; >3% — Poor. For non-brake fluids, the classification is based on fluid quality: >70% — Good; 30%–70% — Fair; <30% — Poor. The test results are clear and easy to understand at a glance. Multi-Brand Brake Fluid Database Supports five brake fluid categories: DOT3, DOT4, DOT5/5.1, ENV4, and ENV6, with data for numerous brake fluid brands built into the device for more targeted testing. Detailed Drivetrain Fluid Testing The drivetrain fluid module includes testing categories for transmission fluid (dry dual-clutch transmission, wet dual-clutch transmission, CVT, automatic transmission, manual transmission, automated manual transmission, and hybrid transmission), as well as differential oil, transfer case fluid, and general reduction gear oil. Testing parameters are matched to the selected fluid type for more accurate results. Gasoline/Diesel Engine Selection The lubricating oil testing function supports two modes: gasoline engine and diesel engine. The corresponding evaluation criteria are automatically matched according to the selected engine type for more accurate testing. 2.8-Inch Color Display The 2.8-inch color display provides a clear and intuitive interface for simple operation. Historical Data Management Automatically stores the 100 most recent test records. Users can view details, delete individual records, or clear all records at once, making it convenient to track changes in fluid condition over time. Chinese/English Language Switching Supports instant switching between Chinese and English to meet the needs of users in different markets.
