Specifications: Micrometer 0-25

Feature:

Outer diameter micrometer the external dimensions measuring instruments, measure the distance between the two sides of the square frame by use of helix principle. Outer diameter micrometer is mainly used for measuring a variety of external dimensions.

Diameter micrometer dividing value is 0.01mm, the upper limit of measurement range is not more than 300mm, divided into a 25mm per specification. Such as 0-25mm, 25-50mm ...... and so on.

Diameter micrometer form shown in the picture: (The picture is for illustration only, does not indicate the detailed structure.)

Instructions for use:

1. Clean the measuring surface before use and correct the zero position. 0-25mm direct alignment zero: 25mm above use the bar gauge aimed at quasi-zero.

2. Zero correction method: If the 0-bit line is not aligned with the baseline, first loose scr
