Coating Thickness Gauge – MiniTest 70

The MiniTest 70 range of Coating Thickness Gauges are small, lightweight and economical.  The instrument has an integrated sensor for those looking for a quick and accurate measurement of non-magnetic coatings on steel and insulating coatings on non-ferrous metal.  The instrument is widely used in the Automotive industry on the shop floor for quick and easy measurements for paint layer thickness (MiniTest 70 E-FN).

The MiniTest 70 coating thickness gauge enables non destructive measurement of

  • non-magnetic coatings (paint, synthetic materials, chromium etc.) on a ferromagnetic substrate (steel)
  • insulating coatings (varnish, enamel, synthetic material etc.) on conductive substrates (aluminium, copper, austenitic stainless steel) (only in the FN type models).

Available in 4 versions:

Minitest 70F:  With statistics display (number of readings taken, mean values, standard deviation, maximum, minimum). Suited only for ferromagnetic substrates (e.g. steel). Measuring range 0 to 3 mm / 118 mils. Enables 1-point and 2-point calibrations.

MiniTest 70 FN:  With statistics display (number of readings taken, mean values, standard deviation, maximum, minimum).  Suited for ferromagnetic substrates (e.g. steel) and also for non-ferromagnetic substrates (non-ferrous metals like aluminium, brass etc.).  Measuring range 0 to 3 mm / 118 mils on steel substrates and 0 to 2.5 mm / 95 mils on non-ferrous metals.  Enables 1-point and 2-point calibrations.

MiniTest 70 B-FN:  Suited for ferromagnetic substrates (e.g. steel) and also for non-ferromagnetic substrates (non-ferrous metals like aluminium, brass etc.).  Measuring range 0 to 3 mm / 118 mils on steel substrates and 0 to 2.5 mm / 95 mils on non-ferrous metals.  Enables 1-point calibrations.

MiniTest 70 E-FN:  Suited for ferromagnetic substrates (e.g. steel) and also for non-ferromagnetic substrates (non-ferrous metals like aluminium, brass etc.).  Measuring range 0 to 3 mm / 118 mils on steel substrates and 0 to 2.5 mm / 95 mils on non-ferrous metals.

Applications

The MiniTest 70 is ideal for non destructive measurement of:

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

Features

  • Accurate coating measurement of up to 3mm(F range) and 2.5 mm(N range)
  • Dual sensor for automatic substrate identification and setting the suitable measuring principle: eddy currents or magnetic induction (not in model F))
  • Wear-resistant probes with long service life
  • Lightweight: only 80 grams
  • Dual sensor for automatic identification of the substrate (FN model). According to the substrate, it adjusts to the appropriate measuring principle: magnetic induction or eddy currents principle.
  • Quick statistics mode to calculate the number of readings, average, standard deviation and min., max. value
  • lightweight: 80 grams / 2.8 oz only
