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

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

• Place the steel ball on one side of the sample and the 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 probe automatically
• The Hall Effect sensor on the probe measures the distance between the probe tip and the steel ball
