Kafer Thickness Gauge
Kafer Model J50R shown above, without guides
Thickness gauges with rollers are suitable for measurement of paper, foil, metal and sheets of fabric, plastic and the like. Unlike other gages fitted with a roller point, these have two rollers: one on top and one on bottom. The material being measured rolls smoothly between these two rollers. The gage is hand held, but could be fastened to a fixture with suitable clamps. The frame must not be modified, however.
They can also be used for measuring wire, rods and extruded stock when the rollers are fitted with guide discs, which keeps the wire "on track."
They're available in many configurations and some can also be ordered in digital versions with SPC output.
These gages are no longer available from us. You can contact the manufacturer for information.
