Minitest 70 F & 70 FN
SIDSP®-Technology
Minitest 70 FN :
Non-destructive measurement of:
non-magnetic coatings such as paint, enamel, chrome and zinc on ferromagnetic bases insulating coatings such as paint, anodic coatings on non-ferrous metal bases
Minitest 70 F :
Non-destructive measurement of:
non-magnetic coatings such as paint, enamel, chrome and zinc on ferromagnetic bases (e.g. constructional steel, car bodies, etc. )
Performance features
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.
