Lever gauges

Precision lever gauge

Design: Housing protects the dovetail guides, chrome-plated, shockproof, bearing for lever gauge shaft in precision ball bearings, movements bearing supported with rubies, automatic switching of measuring direction, housing with three milled dovetail guides for holding the clamping shaft (∅ 8 mm h6), measuring insert 1.6 with 2 mm ∅ carbide ball, rotating outer ring. Supplied with key, in plastic case. Application: To check the concentricity of shafts and sleeves, for centring bore holes, alignment of surfaces and parallelism inspections.

Lever gauge TESATAST

Design: Metal housing, with revolving scale dial and patented shock absorber in the measuring instrument. Two revolving clutch discs in the lifting system protect against overload. Measurement in two directions possible due to automatic switching of the movement. The consistent running direction of the pointer permits error-free reading; not sensitive to magnetic fields, movement with 7 rubies. Ball bearing lever system with 240° pivot range of measuring insert, very low measuring force. Measuring force with measuring insert 12.53 mm: 0.15 N, with 36.53 mm: 0.06 N. Monoblock housing with 3 milled dovetail rails. Supplied with measuring insert M1.4 with ∅ 2 mm, a wrench for measuring insert and a clamping shaft ∅ 8 mm, in plastic case. Application: Ideal for difference measurements, e.g. on the test plate, measurement of shape and position deviations, in particular of concentricity and axial run-out. Note: Suitable measuring inserts M1.4 are found on Ç 4/53.
