The VQ-1 viewer is a 1-axis tool for universal use. It can therefore be installed on traditional machine tools such as lathes, milling machines, slots, drills, grinders, measuring instruments, and others. Its robust die-cast aluminum case allows to have a high resistance to the use in difficult environments such as mechanical workshops, electromagnetic disturbances and its robust keyboard makes it suitable for heavy duty. To further increase its immunity it is equipped with a transparent plastic cover.
