the vertical degree detection

Bathroom and kitchen walls are usually covered with tiles, then you need to check whether the smooth vertical and horizontal wall. We first look at how to check the verticality of the facade tiles. 2M can check whether on foot vertical, but not precise measurement biases, and the use of detection 2M vertical ruler can detect deviations.

The vertical detection test surface abutting the left foot, and then stop itself until the pointer swings after reading the scale pointer value, the value that is measured surface vertical deviation, each cell is 1mm. Vertical facade tiles are generally within 3mm.

2, flatness testing

Detection tile flatness, you can use the vertical ruler detection test can also be added with 2M on foot wedge feeler testing. Detected using the latter method, it will be measured by the foot side of the abutting surface, with its wedge-shaped gap size feeler testing.

To be detected at three points each, the Hand Pallet Truck point and in its place one point 45 ° around the intersection, whichever is the average of three points. Tile flatness error should not exceed 2 mm, height adjacent tiles shall not exceed 0.5 mm.

3, Yang angle squareness checking

Tiling walls, there is a yin and yang angle, need to detect all the yin and yang, yin and yang Square Founder degree angle, angle of yin and yang in accordance with national requirements should not deviate more than 3 mm.
