Lever-Type Test Indicators
Mahr MarTest lever-type test indicators help inspect small deviations where a pivoting contact stylus provides practical access. Compare the India-listed 800 S, 800 SGM and 800 SGE for your alignment or inspection setup.
What can you measure?
Radial and axial run-out
Check indicated variation on rotating cylindrical surfaces or end faces. Establish the rotation axis and set the stylus orientation according to the instrument instructions.
Comparative measurement in confined areas
Compare local surface position with a reference where access suits a lever-type stylus. Contact angle and stylus length affect the indicated displacement.
