KARL DEUTSCH LEPTOSKOP devices can be used to determine the thickness of non-magnetic layers (e.g. paint) on ferromagnetic substrate by means of the magnet-inductive method. The second option is to determine the thickness of non-conductive layers covering non-ferrous base materials utilizing the eddy-current method.

• Large digits facilitate reading of the display.
• Just a "click" and the display shows rotated contents, to make reading of the instrument indications much easier in case of overhead measurement.
• Accurate measurement - even on hard-to-access locations
• Free language selection: German, English, French, Spanish, Italian, Swedish, Polish, Portuguese, Czech, Romanian.

The LEPTOSKOP 2042 is used to measure the thickness of non-magnetic coatings on magnetic substrate (according to DIN EN ISO 2178) and to measure the thickness of electrically non-conductive coatings on non-magnetic electrically conductive substrates by means of the eddy current method (according to DIN EN ISO 2360).

• Large graphic display 48 mm x 24 mm, illuminated

Calibration options

• Calibration ex works, instantly ready for measurement
• Calibration on unknown coating

If the high accuracy of electronic coating thickness measuring instruments is not necessary, the question about a simple and economical alternative sets itself up again and again. For these cases of application the coating thickness gauge "LEPTO-Pen" is the best choice. The LEPTO-Pen works on untempered commercial quality steel substrate according to the known magnetic attraction principle (EN ISO 2178). It is composed of a precision magnet and a mechanical spring balance, the scale of which is calibrated and labelled in µm coating thickness. The handling of the gauge is correspondingly easy.

Technical Data

Model 2091.001: scale 0 to 800 µm / 0 to 30 mils. Measuring range: 10 to 500 µm / 0.25 to 20 mils. Measurement uncertainty within the measuring range: +/- 10% +/- 3 µm.
