BLOW GL-2+ Paint Thickness Gauge for Aluminum and Steel Surfaces

The BLOW GL-2+ paint thickness gauge is a professional-grade diagnostic tool engineered for the precise measurement of coating layers on both steel and aluminum automotive surfaces. This device provides essential data for evaluating the condition of a vehicle's bodywork, enabling users to identify hidden repairs, putty, or secondary paint layers with high accuracy. Designed for efficiency and reliability, it serves as an indispensable asset for automotive professionals, mechanics, and individuals looking to purchase a used vehicle.

Advantages

The primary benefit of the BLOW GL-2+ is its dual-technology sensor, which automatically detects the substrate material, allowing for seamless switching between steel and aluminum surfaces without manual recalibration. Its high measurement precision ensures that even minor variations in paint thickness are detected, providing confidence during vehicle inspections. The device features an intuitive interface that simplifies the reading process, making it accessible for both experienced technicians and casual users. Its compact and durable design ensures longevity and ease of transport, allowing for quick checks in any environment.

Suitable for

• Inspecting used vehicles for accident history
• Verifying the quality of professional paint jobs
• Detecting hidden body filler or putty
• Routine maintenance checks for automotive body shops

This device may not be suitable for measuring non-metallic surfaces such as plastic bumpers, carbon fiber panels, or glass. It is also not designed for industrial applications involving extremely thick industrial coatings or non-automotive materials where specialized ultrasonic thickness gauges might be required.

Key specifications

• Supported materials: Steel, galvanized steel, and aluminum
• Measurement range: 0 to 2000 micrometers
• Resolution: 1 micrometer or 10 micrometers depending on settings
• Display: Backlit LCD screen
• Power source: Battery operated

To use the BLOW GL-2+, ensure the vehicle surface is clean and free of dirt or debris. Power on the device and place the sensor probe firmly against the surface to be measured. The gauge will automatically identify the material and display the thickness value on the screen. For consistent results, take multiple measurements across different parts of the panel, such as the hood, doors, and roof, to compare values and identify potential inconsistencies.

What to consider before purchase

• Verify if your primary use involves metallic surfaces
• Check if the measurement range meets your specific inspection needs
• Ensure the device is calibrated according to the manufacturer's instructions before first use

Usage recommendations

For the most accurate results, perform measurements at room temperature and ensure the sensor probe is held perpendicular to the surface. Regularly clean the probe tip to prevent dust accumulation that could affect measurement precision.
