MT Series Coating Thickness Instrument

Made in GermanyThe MT series is comprised of four different gauges offering different possibilities of processing of measuring values. Different probes are available which can be connected to all gauges. 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-1100 (discontinued)
This gauge is the basic version of the MT series. Its functions are simple and clearly arranged. However, this low-cost version also works with all probes of the range. Thus, special applications, e.g. very thick coatings, can be measured at a reasonable price. The MT-1100 does not offer either a memory or statistics.

MT-2100 (discontinued)
This gauge version also possesses a total memory capacity of 10,000 readings. A complete measuring series can be statistically evaluated. MT-2100 is suitable for users with repeated applications, e. g. electroplated coatings on small objects. Switching off the gauge does not delete calibrations from the memory.

MT-3100 (still available)
MT-3100 also 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.

MT-4100 (discontinued)
MT-4100 offers unique possibilities of data processing. In total, 10,000 measuring values can be stored in max. 99 application memories each with max. 98 batches. Application memories are extremely useful when different measuring tasks requiring different calibrations or probes occur regularly. The selected memory stores the calibration carried out and the probe used. Once MT-4100 is prepared for various measuring tasks, taking a series of readings becomes simple and quick. Permanent calibration can be dispensed with and measuring errors are abolished.
