Application
For measuring particularly large internal and external dimensions.
The TESA UNIMASTER is based on the general concept of an internal micrometer with two-point contact.
By mounting extensions with built-in end dimensions on the measuring element, any dimension within the vast application range can be measured directly.

Execution

• Hardened measuring spindle, thread ground from one piece
• Impact-resistant dial gauge
• Switch easily from internal to external measurement using setscrew
• Gauge block with one flat and one rounded measuring surface
• Extensions with robust protective tube and integrated gauge blocks
• Extensions can be connected via coupling system
• Force de mesure 15 N
• Dial gauge measuring range 0.4 mm
• Micrometer measuring range 25 mm

Advantage

• Very high measuring range possible
• High accuracy
• Heat-resistant
