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.
