The MT-3100 is an advanced coating thickness gauge that offers a range of different probes available to suit your application. In order to select the ideal probe for your application, the thickness of the coating to be measured as well as that of the substrate and the geometry have to be taken into consideration.

Check-Line offers a range of probes suitable for standard as well as for special applications. For measurements on steel, the magnetic induction principle is used allowing measurement of all insulating coatings, e.g. paint, enamel etc., and non-ferrous metals on steel and ferrous metals. Probes working on the magnetic induction principle are referred to as F-probes.

For measurements of insulating coatings on non-ferrous metals, the eddy current principle is used. Probes working on this principle are referred to as N-probes.

MT-3100
The MT-3100 possesses a total memory capacity of 10,000 readings and the possibility to store readings in 10 application memories with 10 batches each. A calibration once performed remains in the application memory. Statistical evaluation of a measuring series allows the user to assess the coating with mean value, max., min., standard deviation and number of readings taken within one measuring series.

Note: The MT Series was previously available in four versions, MT-1100, MT-2100, MT-3100 and MT-4100. As of 2011 the MT-3100 is the only version offered.
