Barcol Impressor

Barcol Impressor is a portable, handheld, indentation hardness tester for rigid plastics like FRP and soft metals like aluminum, copper and other alloys.

Simplicity of the instrument makes it popular and can be operated with no prior experience. It can be used in any position and in any space that will allow clear reach for operator’s hand. Hardness reading is instantly indicated on the dial, which is divided into one hundred graduations. No waiting, pre-loading or separate measurements.

Simply exert pressure against the instrument to drive spring-loaded indenter point into the material. Indenter point must be perpendicular to the surface being tested. On very soft materials, the highest reading should be used since cold flow permits spring loaded indenter point to continue penetration.
