Professional, high-end wall thickness measuring device for non-destructive measurement up to 24mm. The MiniTest 7400 FH allows you to comfortably measure the thickness of non-magnetic materials such as glass, synthetic material, stainless steel and composites. Components with complex geometries can also be measured with ease.
An SIDSP sensor means the MiniTest 7400 FH provides high-precision measurement and reproducibility while compensating for the influence of temperatures in the measuring environment and in the object being measured. Sensors are equipped with carbide tips making them particularly durable.
The MiniTest 7400 FH functions as follows: Thickness is determined by measuring the distance of a reference ball to the sensor tip. The reference ball is attracted by a powerful magnet positioned directly behind the sensor tip. The steel reference balls are treated according to a specialised ElektroPhysik procedure which allows reproducibility of test results of up to 0.5%.
A graphic display and common PC functions (context-specific help, saving of readings in a folder structure, navigating via menus displaying symbols and text) makes the MiniTest 7400 FH extremely easy to use. A user guide is available in 6 languages (German/English/Spanish/French/Italian/Portuguese).
