Scope of application: It is widely used in machinery and industrial processes to accurately measure small linear distances without reading errors. It is an ideal tool for machinery, industrial process and laboratory. High quality material: The digital dial gauge is made of high quality aluminum, stable and durable, high precision, stronger wear-resistant, more corrosion-resistant, durable and has a long service life. Easy to read: the knurled bezel can be rotated 360 degrees, so reading at n any position is zero. The black text on the yellow background is very clear, which can save your time for reading. Easy to use: The dial indicator is specially designed for measurement during processing, layout and inspection. The probe can be rotated 180, freely adjust the measurement direction, and rotate the probe left and right.
