• Installation of frames, shelves, and fixtures

When it may not be suitable

This tool is not intended for high-precision laboratory measurements or industrial-scale surveying that requires digital laser calibration. It may also be less effective for extremely large-scale outdoor civil engineering projects where specialized optical leveling equipment is required.

Key specifications

• Professional-grade angle measurement
• High-visibility spirit vials
• Durable, impact-resistant frame
• Compact and portable design

How to use

To use the Greatwall SJ01, place the base of the level firmly against the surface or edge you wish to measure. Observe the position of the air bubble within the vial; when the bubble is perfectly centered between the two marked lines, the surface is level or at the intended angle. For angle verification, adjust the tool until the bubble aligns with the specific angle markings provided on the device. Ensure the surface is clean and free of debris before placement to maintain maximum accuracy.

What to consider before purchase

• Verify the required measurement range for your specific tasks
• Ensure the physical dimensions of the level fit your workspace
• Check if the level is compatible with the materials you are working with

Usage recommendations

Always store the spirit level in a protective case when not in use to prevent damage to the vials and maintain long-term accuracy. Regularly clean the device with a soft, dry cloth to ensure the vials remain clear and easy to read.
