The "AMTG-2" is a portable feeler gauge. Itis used to measure the thickness of non-magnetic materials, such as plastic,glass, ceramic, aluminum, titanium, copper etc... The accuracy of themeasurement is not affected by the shape of the samples.

It’s designed by basing on the method of the HallEffect. Simple and rapid measure as below:

- Place the steel ball on one side of the sample andthe probe on the opposite side

- Move the sample and let the probe to be the tested position

- The steel ball will be drawn by the probeautomatically
