Model: High-precision feeler gauge measuring instruments with gemstone-supported measuring mechanism in a compact, robust design. The housing and dovetail holding prisms are made from a single piece, which provides exceptional rigidity during clamping. Corrosion protection through matte chrome plating of the housing. 2 1000-readout. TESA - Ruby-supported measuring mechanism with HM measuring ball. Sturdy monoblock housing; non-magnetic. Swiss Made. Note: Additional information DIN 2270: Readout 0.002/0.001 - Deviation range 2 µm, total deviation range 4 µm, measurement reversal range 2 µm. Spare part: Replacement probe with HM or ruby ball available upon request. Delivery includes: Including clamping pin Ø 8 mm. Use: As an accurate comparison measuring device for checking the target dimension deviation for run-out tests, internal measurements, checking parallelism and flatness, as well as for aligning workpieces.
