.The precise process better guarantees the accuracy of the leveling scale:±0.5mm/m

2.In the drop test:3 drops at a height of 1.2m above the ground,the accuracy does not change by more than 0.2mm/m

3.In the high and low temperature test:after a cycle from-18°C to 50°C,the accuracy changes by 0.2mm/m at room temperature.

4.The material used is high-grade aluminium profile,making it lighter,and rust and wear resistant

5.You can choose to combine horizontal,vertical and 45°horizontal bubbles on one level,making it multi-functional,or you can choose only one type of horizontal bubble to meet the needs of customers.

6.You can choose to add magnets to the bottom of the level,which can make the construction and storage more convenient

7.Both ends of the level are equipped with end caps,which can better protect the machine in case of accidental dropping.

8.The bottom of the level is milled to make it smooth and flat.

9.For models over 30cm,the ends of the level are hollowed out to meet the customer's requirements on the wall and to release the hands.
