MiniTest 1100, 2100, 3100, & 4100

The Minitest 1100 - 4100 are small, portable instruments designed for fast, accurate, non-destructive measurement of coating thickness on metals.

Conforms to: ASTM: B 499, B 244, BS: 5411, DIN: 50981, 50982, 50984, ISO: 2178, 2360


MiniTest 1100, 2100, 3100, & 4100

 

Minitest gages are suited to many testing requirements on the shop floor, in production, laboratory or field inspections.

• non-magnetic coatings on steel   • insulating coatings on non-ferrous metals  • non-ferrous metal coatings on insulating substrates

 

Description

MINITEST 1100 - 4100 Series is comprised of four different basic gages thus offering different possibilities of processing coating thickness data. Different probes are available which can be connected to these gages. In order to select the "right" probe, the thickness of the coating to be measured as well as that of the substrate and the geometry have to be taken into consideration.

A full range of probes suitable for standard as well as special applications are offered. For measurement on steel, the magnetic induction principle is used allowing measurements of all insulating coatings e.g. paint, enamel etc. and as well as plating on steel and ferrous metals. Probes that utilize the magnetic induction principle are referred to as F probes. For measurement of insulating coatings on non-ferrous metals, the eddy current principle is used. Probes working on this principle are referred to as N probes. A probe selection chart can be found on the following pages.

Connected to a PC the MINITEST 4100 functions can be controlled through a program making the instrument an integrated part of a network or automated testing unit. The 10,000 reading memory features a variety of statistical data processing methods. MINITEST 1100, 2100, 3100 and 4100 are the only measuring gages at present which can work with different probes between 1 micron and 10 cm. All other new features can be seen in the probe data table. Up to 500 groups of readings can be defined by their individual data and time of measurement and print-out.

The intelligent probes can be adapted for special applications. The parameters of particular samples (shape or coatings properties) are stored in the probe. Our spring loaded probe systems ensure precise, vertical and sure positioning of the probe on flat as well as on round surfaces. The probe tip is manufactured from an extremely hard wear resistant metal, ruby or ceramic material.
