External diameter
Measure shaft and pin diameters between the spindle and anvil faces. Align the contacts with the required measuring section.
TESA · Precision Gages
Select TESA outside micrometers for external diameters, thicknesses and widths. Compare mechanical and digital models, specialised fine contacts and sets within this category.

Measure shaft and pin diameters between the spindle and anvil faces. Align the contacts with the required measuring section.
Measure between accessible opposing faces using the specified measuring force. Contact seating and surface condition affect the result.
Use suitable fine-insert models for notches, keyways, splines and restricted contacts. Confirm the measuring faces against the actual geometry.



| Family / option | Configuration | Selection notes |
|---|---|---|
| Mechanical vernier models | Outside micrometers | Choose individual ranges, units and the required reading graduation. |
| Digital outside models | Digital reading, with or without transmission | Specify the exact data-output configuration. |
| Digital models with fine inserts | Special external contacts | Review access to notches, keyways and splines. |
| Micrometer sets | Several individual measuring ranges | Specify the required range coverage and supplied reference standards. |
| Micrometer heads | Analogue micrometer elements | Select the mounting and measuring arrangement for integration into a fixture. |
This comparison describes product families and configurations. Confirm the exact range, permissible error, accessories and documentation with the selected part number. Display resolution alone does not state measurement accuracy.
List the actual dimensions to be measured. A set covers several individual ranges rather than one continuous instrument stroke.
Specify flat, narrow or other contact needs and consider deformation of the workpiece.
Include the appropriate reference, support and data connection. Specify the required calibration documentation.
Outside micrometers measure external dimensions. Review the IMICRO and bore-gauge category for internal diameters.
They provide contact access to selected notches, keyways and splined features. Verify contact seating and clearance before selecting a model.
The range includes digital models with and without transmission. Confirm the exact variant and compatible connection.
List the dimensions and individual ranges needed, together with references, quantity and documentation. Confirm the contents of the proposed set.
Minimum and maximum diameter or thickness, tolerance, contact geometry, individual ranges, quantity and data needs.
India availability, supplied accessories and lead time are confirmed with the quotation.
