TQC SHEEN VF6500 Barcol Hardness TesterPortable
The Impressor is a convenient tool for testing the hardness of aluminum, aluminum alloys, copper, brass and other materials including plastics and fiberglass. The instrument is designed for use on fabricated parts and assemblies as well as on raw stock.
- Easy to Use
- Official Barcol impressor scale, for testing of:
- Aluminum Alloys
- Soft Metals
- Fiberglass Sheet, Tanks, Surfaces
- Fire Department Ladders
- Composite Materials
- Rubber or Leather
The Impressor is best suited for testing homogeneous materials. Materials of granular, fibrous or coarse structure will produce a wide variation in hardness readings because of the small diameter of the indenter point.
For accurate readings, material should be at least 1/32 thick and large enough for a minimum distance of 1/8³ in any direction from the indenter point to the edge of the specimen. The testing area should be smooth and free from mechanical damage.
