About Precision Coating Thickness Gauge – MiniTest 7400

The MiniTest 7400 is a high end dry film coating thickness gauge with a wide range of external interchangeable probes and memory for up to 250,000 measurement values and 500 measurement groups.  The instrument enables the user to take a wide range of measurements, from the thinnest coatings in the sub-micrometer range (e.g. galvanised coatings), difficult geometries of the objects to be measured (e.g. measurement of steel pins, measurement to be taken in recesses and holes, etc.) down to thick coatings (e.g. flame retardant coatings in steel constructions, rubber coatings etc.).

The probes (sensors) supplied with the instrument are extremely accurate and reproducing results on account of their manufacturing process. Despite high accuracy the sensors are wear resistant and withstand even years of use on rough surfaces. Each sensor is subject to a fully automatic factory test and provided with 50 calibration points for correction of even the slightest deviations.  Each sensor is encoded with temperature compensation for automatic correction of the effect of temperature on the readings.

Features & Benefits

  • Precision in coating thickness measurement of up to 100 mm / 4 inches
  • Increased accuracy and reproducibility by sensor-integrated digital signal processing (SIDSP®)
  • Universal probes with automatic substrate detection for quick measurements on steel and nonferrous metals
  • Wear resistant probes with practically unlimited service life
  • Optimal temperature compensation
  • High precision characteristic curves with up to 50 data points in the factory calibration
  • Storage for up to 100000 values
  • User guidance in 4 languages, others under preparation
  • Infrared data transmission (IrDA) to PC and printer

Applications

Non-destructive coating thickness measurement of:

  • Non-magnetic coatings like varnishes, enamels, chromium and zinc on ferromagnetic base materials (e.g. steel)
  • Insulating coatings like varnishes and anodising aluminium and non-ferrous metals (e.g. aluminium)
