Line level Laserliner MasterLevel Box — LCD display, AAA 1.5V, 59×59×28 mm, black/grey

Laserliner MasterLevel Box is a compact digital line level with an integrated LCD display designed for precise alignment and levelling tasks in carpentry, installation and general trade work. The instrument measures 59 × 59 × 28 mm and is powered by AAA 1.5 V batteries. Its square design and clear readout enable quick reading of angles, bubble positions and transferred references, while built-in magnets secure the device to metal surfaces for hands-free operation. The housing is largely made from recycled plastic, contributing to a more sustainable tool choice.

Advantages

The MasterLevel Box offers a practical 360° angle display, a reference function to transfer angles and an automatic flip of the display for overhead measurements so values remain legible in any position. A hold function freezes the current measurement on the screen and a calibration function ensures high measuring accuracy and precise adjustment to the measurement area. Strong adhesion magnets provide secure placement on metal parts, and the compact square form factor fits easily into a toolbox or pocket.

Suitable for

• Carpentry and joinery for aligning beams, frames and furniture
• Installation work such as mounting shelves, cabinets, pipes and fixtures
• Tiling and flooring where accurate slope and level are required
• Metalworking and HVAC tasks that demand hands-free levelling on metal surfaces
• DIY and general alignment tasks on construction sites and workshops

How to use

Place the MasterLevel Box on the surface to be measured or attach it to a metal surface using the built-in magnets. Switch on the device and read the angle or bubble position on the LCD; the display automatically flips for overhead measurements. Use the reference function to set and transfer a specific angle, and press the hold function to lock a displayed value for later transcription. If accuracy adjustments are required, perform a calibration according to the instructions to adapt the instrument to the measurement area. Replace the AAA batteries when the display indicates low power.

Usage recommendations

For best results, ensure the contact surfaces are clean and free of debris before positioning the level. When measuring on metal, verify the magnets have full contact to avoid slippage. Calibrate the device periodically, especially after impacts or temperature changes, and store it in a dry place when not in use. Use fresh AAA batteries for optimal display brightness and reliable measurement.
