最近,我们根据水平仪的原理,制成墙面垂直度检查仪。这种仪器用水泡代替线锤,检查时,墙面倾斜数值可以从水泡上直接读出,尺身为折叠式。经实际使用证明,这种仪器测量精确,使用方便。具体制作事项如下,见图1。尺身整体加工后锯成上、下两 Recently, according to the principle of the spirit level, we have built a wall verticality tester. This instrument uses blisters instead of a line hammer. When checking, the wall tilt value can be read directly from the blisters and the ruler is folded. The actual use shows that this instrument is accurate and easy to use. The specific production items are as follows, see Figure 1. The whole body of the ruler is sawed into upper and lower
