The Autool TG501 is a paint thickness gauge for measuring coating thickness on both ferro (Fe) and non-ferro (NFe) metal substrates. The device operates based on magnetic induction for steel and the eddy current principle for aluminum and other non-ferro metals, with automatic substrate recognition. With a measuring range of 0 to 2,000 µm, a resolution of 0.1 µm up to 100 µm, and an accuracy of ±(3%+1 µm), the meter is suitable for inspecting original paint, repaired bodywork, and filler layers on car bodies.
During measurement, the sensor on the underside of the device is placed against the surface, after which a measurement value appears on the LCD screen within about half a second. The TG501 automatically switches between Fe and NFe mode based on the detected substrate and displays the value in µm, mm, or mil. The screen features automatic screen rotation and has a backlight for measurements in poorly lit areas. The meter includes a zero calibration for compensation on a reference surface and can store up to 80 measurements for later reading.
ADVANTAGES
IMPORTANT NOTES
Applications and functionalities
The Autool TG501 supports the following measurement and reading functions:
- Ferro measurement (Fe): Determines the coating thickness on steel and other magnetic surfaces via magnetic induction, useful for inspecting bodywork on cars.
- Non-ferro measurement (NFe): Measures layer thickness on aluminum and other non-magnetic metals, such as engine hoods and panels of aluminum bodies, using the eddy current principle.
- Automatic mode detection: Automatically detects whether the substrate is ferro or non-ferro and selects the corresponding measurement method without manual setting.
- Unit switching: Switches between µm, mm, and mil via the UNIT button for display according to the desired standard.
- Zero calibration: Sets the meter on an uncoated reference so that deviations caused by temperature or material are compensated.
- Measurement value storage: Stores up to 80 measurements with sequence numbers, allowing measurement series per panel or vehicle to be reviewed.
- Clear measurement value: Deletes individual or all stored values via the trash button.
Special functions and capabilities
The TG501 stands out with the following features:
- Automatic screen rotation: The display rotates the measurement value with the device orientation, keeping the value readable during measurements on the side or underside of a vehicle.
- High-precision sensor with fast response: Provides up to 2 measurements per second, allowing a panel to be checked at multiple points in a short time.
- Backlight with dim function: Suitable for use in dark workshops and under tarps during appraisal or damage repair.
