Model: High-precision feeler gauge measuring devices with gemstone-supported measuring mechanism in a compact, robust design. The housing and dovetail holding prisms are made from a single piece, resulting in particularly high rigidity against bending. Corrosion protection is provided by a matte chrome finish on the housing. Features a 1 100 reading. TESA ruby-supported measuring mechanism with a carbide measuring ball. Sturdy monoblock housing; non-magnetic. Swiss Made. Note: Additional information DIN 2270: Reading 0.01 - deviation range 10 µm, total deviation range 13 µm, measurement value reversal range 3 µm. Spare part: Replacement probe with carbide or ruby ball available on request. Delivery includes: Including clamping pin Ø 8 mm. Use: As an accurate comparison measuring device for checking the specified dimensional deviation for run-out tests, internal measurements, checking parallelism and flatness, as well as for aligning workpieces.
