MiniTest 70FN

Overview

Application

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

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.
• Quick statistics mode to calculate the number of readings, average, standard deviation and min., max. value
• lightweight: 80 grams only
