MiniTest 7200 FH/MiniTest 7400 FH

Working on the magneto-static principle, the gauges enable quick and easy measurement on non-ferromagnetic materials. The measuring system consists of a handy sensor, which is connected via a cable to the base and display unit for visualization and processing of readings. For measurement, specially treated target balls made of a ferromagnetic material are used as a reference. For measurement, a target ball is placed on the material to be measured so that the material thickness between target ball and sensor will be measured. The measuring system comes with sensor stand (available as an option) to add additional comfort of handling during measurement

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   7200FH   plus   statistical   graphing,   real time trend, data base with up to 200 batches  and  a  larger  memory  for automatic  storage  of  up  to  240,000 readings,   e. g.   1,200   readings   per batch.

Provides Higher Accuracy The MiniTest 7200 FH/MiniTest 7400 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.
Two Sensors to Choose From  In  order  to  maximize  the  accuracy of  readings,  two  easily  interchangeable sensors with a hardened tip and  a  variety  of  ball  sizes  are  available to  cover  the  various  thickness  ranges.
  • The FH 4 sensor uses steel balls to measure  from  0  to  6  mm  and  magnetic  balls  to  measure  up  to  9  mm.
  • The  FH  10  sensor  uses  steel  balls  to measure from 0 to 13 mm and magnetic balls to measure up to 24 mm.

The  two  sensor  models  are  interchangeable and can be connected to any of the two gauge models.
