FH Series
Precision Magnetic Thickness Gauge

Models
FH-7200 - Basic Model
FH-7400 - Enhanced display and statistics

Measuring Ranges
FH 4: 0.00 - 0.16" / 0 - 4mm
FH 10: 0.00" - 0.39" / 0 - 10mm

The FH-7200 & FH-7400 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

Model FH-7200 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.

Model FH-7400 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.

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).
