Features Portable. Convenient.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. 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. Ordering Guide GYZJ-934-1For 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). GYZJ-934-1-1A 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. GYZJ-935for the softer plastics and very soft metals. GYZJ-936For extremely soft materials such as lead, linoleum and leather. Operation and Calibration OperationConversionCalibrationSimply 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.
