Max. thickness (ferrous met.)

The maximum coating thickness that the instrument can detect when measuring on ferrous metals such as steel. With a larger coating thickness, the thickness gauge sensor simply cannot “catch” on the metal surface under the paint, and effective measurement will not be possible. This parameter is indicated in micrometers — thousandths of a millimetre; the larger it is, the more versatile the device is, the wider the possibilities for its use. On the other hand, a large maximum measurement thickness can adversely affect the accuracy when measuring small values.

For modern thickness gauges, the maximum thickness up to 1000 microns is considered small, from 1000 to 1500 microns — small, from 1500 to 2000 microns — medium, more than 2000 microns — significant. In the most advanced professional-level models, this figure can reach 20 – 30 cm.

Max. thickness (non-ferrous met.)

The maximum coating thickness that the instrument can detect when measuring non-ferrous metals such as aluminium alloys. With a larger coating thickness, the thickness gauge sensor simply cannot “catch” on the metal surface under the paint, and effective measurement will not be possible. This parameter is indicated in micrometers — thousandths of a millimetre; the larger it is, the more versatile the device is, the wider the possibilities for its use. On the other hand, a large maximum measurement thickness can adversely affect the accuracy when measuring small values.

Max. error

The maximum measurement error provided by the device, in other words, the largest deviation from the real value of the measured value that may occur during the measurement process. The smaller this indicator, the more accurate the device, the smaller the error it gives in the measurement process; on the other hand, high accuracy has a corresponding effect on cost.

Specifically, in thickness gauges, an accuracy of 10% is considered low, 5% is average, 3% is good, and less than 3% is excellent.

Memory

The maximum number of measurement results that can be simultaneously stored in the instrument's built-in memory. This number can vary from 10 – 20 in low-cost models to several thousand in the most advanced ones.

Volumetric memory allows you to simultaneously store a lot of information, but affects the cost of the device.
