The third-order ruler currently in use is made of zinc white copper, stainless steel, brass and the like. The third-line ruler is a rigid ruler whose engraved line is on two inclined faces at an angle of 45° to the bottom surface. 1020mm engraved line, one side has a division value of 0.2mm and the other side has a length of 1mm. On the back of the third-line ruler Flanged rails, two 7x magnifiers can be moved along the measuring axis on the rail for magnification The third-line ruler and the line spacing of the ruler. In the back of the ruler, a range of (-30~ 50) °C or (-35~45) °C mercury thermometer with a division value of 0.5 °C. The outline structure of the third-line ruler is shown in Figure 1. 1-line surface; 2-rail; 3-magnifier; 4-thermometer Figure 1 Third-line ruler outline structure4 Metrological performance requirements4.1 The dimensions of the third-line ruler and the length of the scribe line are shown in Table 1. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 71-2005_English be delivered?Answer: Upon your order, we will start to translate JJG 71-2005_English as soon as possible, and keep you informed of the progress.
