Coating thickness gauge MiniTest 650

coppersteelfor non-ferrous materials

Product information
The MiniTest 650 is robust and perfectly suited to coating thickness measurement in harsh conditions and on abrasive surfaces.

• Sandblasted steel
• Heavy duty corrosion protection in ship building
• Offshore installations and mining facilities
• Plasma-sprayed surfaces

MiniTest 650 – The Robust coating thickness measurement gauge
The MiniTest 650 has a fixed external probe for all non-magnetic coatings on steel and all insulating coatings on nonferrous metals. For measurement on rough steel surfaces the F probe comes equipped with special wear protection to ensure long service.
