The ElektroPhysik FH Series MiniTest 7200 and 7400 FH Magnetic Wall Thickness Gauge 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 FH Series 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
ModelFH-7200offers 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.
ModelFH-7400offers 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.
5 Probes to Choose From
In order to maximize the accuracy of readings, five (5) easily interchangeable probes with a hardened probe tip and a variety of ball sizes are available to cover thickness ranges from 0 - 6mm up to 0 - 24. Refer to table below for detailed description of the various measuring ranges, ball diameters and ball type (non-magnetic and magnetic). Use of magnetic balls allow for measurement of thicker materials as both the probe and the ball have their own individual magnetic attraction properties.
Probes are required for measuring and are sold separately
The following accessories will be supplied based on the Probe Type purchased.
