Autool AS505 | Transmission Fluid Tester

The Autool AS505 is a transmission fluid tester that analyzes the condition of the fluid in a gearbox. The device uses an optical sensor to measure the light transmittance of the oil, determining the level of contamination and aging. In addition to clarity, an integrated sensor also measures the temperature of the fluid for a complete analysis.

The tester is equipped with a flexible probe with a length of 800 mm, made of oil- and corrosion-resistant PTFE. Results are displayed within seconds on an illuminated 2.8-inch LCD screen. The display includes light transmittance in percent, an analog bar graph, fluid temperature in °C or °F, and a clear indication whether the fluid is in good condition, needs attention, or must be replaced.

Application and functionality:

This instrument is designed for quickly and easily checking the quality of transmission fluid, which helps with preventive maintenance and preventing damage to the gearbox.

• Optical measurement: An optical transmitter and receiver in the probe tip measure the amount of light transmitted through the fluid to detect contamination and degradation.
• Temperature measurement: The built-in temperature sensor displays the operating temperature of the fluid, which is important information for diagnosing the transmission system.
• Immediate results: The large display immediately shows a clear and easy-to-interpret result, including a maintenance recommendation.
• Flexible probe: The long and flexible probe ensures that the fluid in most vehicles can be easily reached through the dipstick opening.

Compatible systems and applications:

The AS505 is suitable for professional use in garages and for vehicle owners who perform maintenance themselves.

• Vehicle system: Automatic transmission systems
