The BB 20 measuring instrument is used to determi-
ne different coating thicknesses . The measuring ins-
trument works according to the magnetic induction
principle or according to the eddy current principle .
The appropriate mode can be selected via the menu .
All measuring instruments comply with the following
industry standards:
• GB/T 4956-1985
• GB/T 4957-1985
• JB/T 8393-1996
• JJG 889-95
• JJG 818-93
Features
• M easurable coatings: non-magnetic coatings (e.g.
paint, zinc on steel); insulating coatings (e .g . paint,
anodising coatings) on non-ferrous metals .
• S imple, intuitive menu guidance
• 2 measurement modes: CONTINUOUS and SINGLE
