Interapid Dial Lever-Style Variance Indicators
Measure larger ranges than with our other lever-style indicators. Also known as test indicators, these have a lever-style contact point that pivots as it comes into contact with a surface and a balanced dial with positive values on one side and negative values on the other side. Rotate the dial face for viewing at multiple angles. Bearings are jeweled for high sensitivity, wear resistance, and a long service life. A revolution counter helps you keep track of dial revolutions.
Mounting stem adapters (sold separately) increase the diameter of your indicator mounting stem from 5/32" to 3/8" so it can be mounted to holders that fit 3/8" diameter stems.
