| MiniTest 3100 |
 |
|
| The Minitest 3100 is a small, portable instrument 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 |
 |
The Minitest 3100 gage is 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 |
| |
Minitest 3100 MINITEST 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. Statistiacal 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.
Different probes are available which can be connected 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 3100 function 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 3100 is the only measuring gage 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 springloaded 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. |
