BoFeng DZJ3 Laser Plumb Bob

Model: DZJ3

Product Name: Laser Plumb Bob

Performance Features:

High laser brightness, good monochromaticity.

2) An integrated body with stable and reliable performance.

3)  Semi-conductor laser with detachable filter plate

4) Square-shaped laser target for easier user operation;

5)         The down-point auto-delayed shutdown;

6) The laser spot is pre-focused, eliminating the need for adjustment and enhancing measurement accuracy.

Function and Application:

1) Used for measuring minute horizontal deviations relative to the plumb line and for transferring plumb line points.

2) Measurement of the vertical profile of objects and vertical transmission of orientation.

3) Widely used in high-rise construction, skyscrapers, chimneys, and elevators.
