| Portable | 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.
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. |

Three Models Available |
GYZJ 934-1 for soft metals such as aluminum and its alloys, brass, copper, and some of the harder plastics and fiberglass. Approximate range 25 to 150 BrineIl (10 mm ball 500 kg load). This unit meets American Society for Testing and Materials Standard ASTM D-2583. Price starts at $774.00. GYZJ 935 for the softer plastics and very soft metals. Price starts at $774.00 GYZJ 936 for extremely soft materials such as lead, linoleum and leather. Price starts at $886.00 We will be glad to recommend the most suitable model upon receipt of sample materials. |

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, which is divided into one hundred graduations. No waiting, pre-loading or separate measurements. For accurate readings, material should be at least 1/32" thick and large enough for a minimum distance of 1/8" in any direction from the indenter point to the edge of the specimen. The testing area should be smooth and free from mechanical damage. Simply exert a light pressure against the instrument to drive the spring-loaded indenter point into the material. The indenter point must be perpendicular to the surface being tested. On very soft metals, the highest reading should be used since cold flow permits the spring-loaded indenter point to continue penetration. |
