Coating thickness measurement		MiniTest 650
Rugged coating thickness gauge
For any non-magnetic coatings on steel such as paint, enamel, chrome, zinc, etc.
For any insulation coatings on non-ferrous metals such as paint, anodising, ceramics on
aluminium, copper, zinc die-cast, brass, etc.
Ram-and impact-protected through rubber rimmed casing
Wear-resistant carbide metal sensor tip
Description
The battery-operated gauge features a backlit display and a one meter sensor cable.
The newly developed one pole sensor is made of a wear-and-tear resistant carbide material
to ensure a virtually unlimited life cycle under normal condition use.
An optimal ram-and impact-protection is provided through the rubber rimmed casing. Via an USB
interface, the MiniTest 650 can be connected to a PC for on-line measurements or display of the
statistics.
The MiniTest 650 Series is available in three models;
The MiniTest 650 F is supplied with a Magnetic Induction sensor for measuring non-magnetic coatings
over ferrous substrates.
The MiniTest 650 N is supplied with an Eddy Current sensor for non-conductive coatings over non-
ferrous substrates.
The MiniTest 650 FN is a dual sensor for measuring coatings over both ferrous and non-ferrous substrates.
This sensor has a auto-recognize feature whereby it recognizes the substrate and automatically switches
to the appropriate measuring principle.

Special feature of the FN model:
Its dual sensor identifies the substrate material. Upon contact with the surface, the gauge automatically switches to the
suitable measuring principle based on your application. The measuring principle conforms to the DIN, ISO, BS, and
ASTM norms and standards.
