High-precision Thickness Measurement

  • On non-ferrous Materials
  • Measures up to 10 mm thick
  • Ideal for Bottles, Aluminum Cans, Glass and Plastic Components with Complex Shapes
  • Menu-controlled User Interface
  • Context-sensitive on-line Help
  • SPC Capabilities
High-Accuracy Thickness Measurement
The MiniTest 7400 FH/MiniTest 7200 FH is a portable thickness measuring device that offers the capability to precisely measure materials up to 10 mm thick. The small size and portability of the device enables it to be operated in production areas and quality laboratories. The MiniTest 7400 FH/MiniTest 7200 FH provides easy, non-destructive and highly accurate thickness measurement on all types of non-ferrous products, regardless of their size, shape, and material.

It is ideal for applications where accurate measurement of sharp corners, small radii and/or complex shapes are required.

 

Two Models
MiniTest 7200 FH offers measurement capabilities including real-time thickness measurement, display of minimum and maximum readings, an offset mode, and automatic storage of up to 100,000 values. MiniTest 7400 FH offers the same capabilities as the MiniTest 7200 FH plus statistical graphing, real time trend, data base with up to 200 batches and increased automatic storage of up to 240,000 values. e.g. 1200 per batch.

 

 

SIDSP Provides Higher Accuracy
The MiniTest 7400 FH/MiniTest 7200 FH Gauging Systems incorporate sensor- integrated digital signal processing (SIDSP). All measuring signals are digitally created and completely digitally processed inside the sensor itself. Only completely processed digital readings are transferred to the base unit for display, statistical analysis, and storage. Unlike analog devices, error influences on the measuring data during transfer are totally excluded.

 

 

Two Probes to Choose From
In order to maximize the accuracy of readings, two easily interchangeable probes with a hardened probe tip and a variety of ball sizes are available to cover thickness ranges from 0 to 4 mm (FH 4) and 0 to 10 mm (FH 10).

 

 

Advanced Reference Ball Design
The MiniTest 7400 FH/MiniTest 7200 FH utilize specially treated reference balls featuring an increased dimensional precision. Balls of this design result in improved measurement reproducibility of up to 0.5 %. Reference balls are available in 1.5 mm, 2.5 mm, 4.0 mm (FH 4), and 2.5 mm, 4 mm, 6 mm and 9 mm sizes (FH 10).
Reference balls with a specially coated finish and dimensional precision to obtain maximum reproducibility of readings.

 

 

Innovative menu Control and Data Filing System
The MiniTest 7400 FH/MiniTest 7200 FH feature an easy to understand, menu-driven operator interface and data filing system, similar to common PC applications. Operational assistance is always available via context-sensitive help topics.
