External dimensions
Measure outside diameters, widths and thicknesses using the external measuring jaws. Select jaw length and range for the component.
TESA · Precision Gages
Vernier, Dial & Digital Calipers
Compare TESA vernier, dial and digital calipers for external, internal, step and depth measurements. Select the measuring geometry and range before choosing the reading system or data connection.
What can you measure?
Internal dimensions
Measure accessible internal diameters and widths using suitable inside jaws. Jaw geometry determines access and the minimum feature size.
Depth and step dimensions
Measure recess depth or step height with the appropriate rod, hook, bridge or step faces. Check the features provided on the selected model.

Models and measurement options
| Family / option | Configuration | Selection notes |
|---|---|---|
| TWIN-CAL IP67 | Universal digital calipers | Compare variants with or without data transmission. |
| TWIN-CAL IP40 | Universal digital calipers | Choose the protection rating for the actual environment. |
| TESA-CAL IP67 | Universal digital calipers | The manufacturer lists these variants without data transmission. |
| Vernier and dial models | Mechanical reading systems | Select scale units, jaw arrangement and measuring range. |
| Workshop and depth models | Larger jaws or dedicated depth geometry | Review short measuring faces, hooks and rotary-stop configurations. |
| Special calipers | Groove, knife-edge or steel-tip arrangements | Specify the contact geometry shown on the drawing. |
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.
What to consider before choosing
Contact geometry
Identify the external, internal, step or depth feature and the available contact surfaces.
Range and tolerance
Provide minimum and maximum dimensions. Compare permissible error and the measurement method with the part tolerance.
Environment and data
Select protection and output by exact variant. Include a compatible connection and receiving software when readings must be recorded.
Frequently asked questions
Does every digital TESA caliper transmit readings?
No. The current range distinguishes TWIN-CAL variants with or without transmission and TESA-CAL IP67 variants without transmission. Specify data output explicitly.
When should I use a dedicated depth caliper?
Use a dedicated depth arrangement when the reference surface, recess access or required contact geometry is better served by a bridge, hook or depth measuring face.
Can a standard caliper measure grooves?
Only if the measuring contacts reach the intended faces correctly. Compare the special groove and knife-edge models against the drawing.
What is needed for a complete quotation?
Provide range, tolerance, jaw or depth geometry, reading preference, units, quantity and any data-transfer requirement.
