The Autool AS505 Transmission Fluid Tester is a professional-grade digital diagnostic tool specifically engineered to evaluate the health and quality of automotive transmission fluid. Using an advanced optoelectronic sensor, it measures fluid transmittance (transparency) to detect impurities, deposits, and contaminants that can indicate mechanical wear or fluid degradation. Key Diagnostic Features High-Precision Optical Probe: Features an integrated optoelectronic sensor that detects the cleanliness and transparency of the fluid with high accuracy. Integrated Temperature Sensor: Displays real-time transmission oil temperature in both Celsius (°C) and Fahrenheit (°F), allowing users to assess the status of the lubrication system. Intelligent Sound Alarm: Provides instant feedback based on fluid transmittance levels: 100% – 50%: Fluid is in good condition; no change required. 50% – 30%: Warning displayed; change is recommended soon. Below 30%: The device emits a “beep” alarm and displays an alert, signaling the fluid must be replaced immediately for safety. Flexible 800mm Probe: The long, flexible hose is made of PTFE (Teflon), which is highly resistant to oil, oxidation, and corrosion.
