Easy to use. No experience required.
Can be used in any position and in any space that will allow for the operator's hand. The hardness reading is instantly indicated on the dial (displays 100 graduations). No waiting, pre-loading or separate measurements.
For soft metals such as aluminum and its alloys, brass, copper, and some of the harder plastics and fiberglass. Approximate range 25 to 150 Brinnell (10 mm ball 500 kg load).
A variation of the 934-1 that has a "flat bottom" shaped support leg. This is used to sit on top of the crest of the round rung of a ladder such as a fire department ladder. Approved by the NFPA.
for the softer plastics and very soft metals.
For extremely soft materials such as lead, linoleum and leather.
Operation and Calibration
|Simply exert alight pressure against the instrument to drive the spring-loaded indenter point into the material.||See the typical readings of aluminum alloys and review the approximate conversion curves for the barcol impressor models.||Follow the step by step calibration procedure for the Barcol Impressor. Use the included tool to begin the procedure.|
