Specification Brand : TECHTONGDA BulletPoint1 : Excellent design: The dial plate base is a universal magnetic base, which can be rotated 360°, can be fine-tuned, has locking bolts, can be adjusted according to needs, and is very flexible. BulletPoint2 : Powerful function: The roller with double grooves can be lifted up and down and the height of the roller can be adjusted through this handle according to the diameter of the workpiece to be measured. BulletPoint3 : Easy to operate: Rotate the handle by hand to measure the workpiece to be measured, measure its runout, and read through the meter. BulletPoint4 : High precision: The machine is equipped with a 0.01mm dial indicator, which can be accurately measured, with high precision and fast measurement. BulletPoint5 : Wide used: it can measure the outer circle and inner circle of the workpiece at the same time. Always used for centrifugal pumps, compressors, fans, generators and other rotating equipment to find the concentricity of two axes work.
