The MiniTest FH Series is a professional, high-end wall thickness measuring device for non-destructive measurement up to 0.94" (24mm). The user-friendly unit 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. A SIDSP sensor means it provides high-precision measurement and reproducibility while compensating for the influence of temperatures in the measuring environment and in the object being measured. An industry standard for plastic container manufactures and well suited for applications that are difficult or impossible to measure with ultrasonics.
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 a larger memory for automatic storage of up to 240,000 readings, e. g. 1,200 readings per batch.
Easily interchangeable sensors with a hardened tip and a variety of ball sizes are available to cover the various thickness ranges. The FH 4 type sensors use steel balls to measure from 0 to 6 mm and magnetic balls to measure up to 9 mm. A special FH 4 sensor allows to work with a 1mm steel ball which can be introduced in small cavities. The FH 10 type sensors use steel balls to measure from 0 to 13 mm and magnetic balls to measure up to 24 mm. All sensor models are interchangeable and can be connected to any of the two gauge models.
The MiniTest FH Series determines thickness 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. Can perform non-destructive wall thickness measurement of:
