Tripods for measuring heads of types ШМ-IIН and ШМ-IIB are designed for mounting on them measuring heads with a division value of 0.01 mm.
Tripod type ShM-III - for installing measuring heads with a division value of 0.01 mm or more.
There is a permanent magnet built into the base of the tripod. A coupling with a rod with a measuring head attached to the end moves along the cylindrical column of the tripod.
The magnetic base allows you to install the tripod on inclined and vertical planes without additional fastening.
Tripods of types ШМ-IIH and ШМ-IIB have devices for precise adjustment to size (for microfeeding). The base of the ШМ-IIВ tripod has the shape of an equilateral triangle with a side of 300 mm, at the corners of which three magnetic supports are located.

Example of designation: A tripod with a magnetic base for measuring heads with a division value of 0.01 mm, with a low column type ШМ-IIН.

Control and measuring instruments (instruments) are equipment without which it is impossible to imagine modern production today. Measurements are required at every production stage and in a wide variety of industrial applications. That’s why the measuring instruments are so diverse, including tripods types ШМ-IIН, ШМ-IIВ, ШМ-III GOST 10197-70, micrometers, mikators, straight and measuring rulers, pedometers, inclinometers, thickness gauges, hardness testers, microscopes, calipers, etc. d.
