INTERAPID 312 1,6 mm, 0,01 mm, Ø 30 mm

Measuring devices with particularly large measuring span - ideal for difference measurements, e.g. on the test plate - Measurements of form, position and positional deviations, in particular radial and axial run-out
Design: Lateral + perpendicular
- Measurement in 2 directions through automatic automatic changeover in the measuring unit
- Pointer always moves in the same direction
- Reliable reading due to additional pointer as rotation counter for the main hand
- Movement fitted with rubies
- Ball-bearing lever system with 210° swivelling range of the measuring insert
- Very low measuring force
- Particularly robust due to the all-metal design
- Swivelling clamping shaft Ø 4 mm
- Delivery: In case, measuring probe with ball Ø 2 mm, Clamping shaft Ø 8 mm, spanner disc

Measuring insert with 12° angle of attack
The INTERAPID 312 lever probe measuring devices are designed so that with an angle of incidence α of 12° of the measuring insert to the workpiece surface, the measuring value is correct without correction.
For any other angle of incidence, including the parallel position of the measuring insert to the workpiece surface, the measured values read must be corrected.
