Eurotherm Impressor Models:

(GYZJ-934-001, GYZJ-934-001-0-01, GYZJ-935, GYZJ-936)


The Impressor is intended for handheld testing of hardness for aluminum and aluminum alloys, soft metals, plastics, fiberglass, rubber and leather. Harder materials cannot be tested with the Impressor. For information on the available models, refer to the current revision of our product guide.

 

To test a surface, place the indenter point and the leg of the impressor on the same plane of the surface. To insure reading accuracy, make certain that no indentations from previous use are within 1/16th of an inch of the present indenter point position. Readings should not be taken on both sides of the 1/32nd inch-thick test disks. Readings taken on top of old indentations will adversely affect the accuracy of the reading. An ample supply of appropriate test disks should be maintained for these reasons.

 

Press down firmly, but carefully, on the impressor handle. Observe the indicator, noting the peak reading. For softer materials there will be some falling-off of the reading from the peak value. This is normal and is due to the nature of the materials being tested.

 

As a general rule, you should increase the number of readings taken as the softness of the materials being tested increases. Refer to the table below for recommended minimal numbers of readings for various materials using the Model GYZJ 934-1. Though specific numbers for Models GYZJ 935 and GYZJ 936 are not included due to correlation difficulties with softer materials, the numbers suggested for reinforced plastics serve as a starting point for softer materials.


Lightweight.
Only 1 lb. 2 oz.

The Impressor weighs only 1 lb. 2 oz. The entire Impressor package comes complete with carrying case, adjusting wrench, one GYZJ-250 (87/89) standard test disk and one GYZJ-78 (43-48) standard test disk and two spare indenter points. Shipping weights = 4 pounds, box = 13 x 13 x 7 inches.

 

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.

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.
