Quantity
Add Quotation


Overview

Application

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

Scope of delivery

  • MiniTest 70 device with integrated sensor
  • Operating instructions
  • 1 AA cell, type LR06
  • Zero reference plate(s)
  • Control standard
  • Belt pouch
