YN31108-A insulation wall thickness projector (mechanical) 
 Overview: 
 The cable cross-section projector is specified special instruments for wire and cable industry to measure the cable cross section of the Shanghai Electric Cable Research Institute. Quality of the instrument optical system, clear lens imaging magnification ratio accurately, the transmitted light illumination, contour measurement error small dry 0.08%; measurements show the value of error of up to (4 + L/25) μm, L is measured length ( Unit: mm)
