ZWICKROELL GMBH & CO. KG

The Shore A, D, B, C, D0, 0, 00, 000 electronic hardness tester is ideally used for applications that are concerned with determining the hardness rating of plastics ans rubber. This unit operates in accordance to the standards set by the ISO 7619-1, ASTM D 2240, ISO 868, NFT 51109 and BS 903 Part A26. The testing procedure, however, deems that a 35 mm plane parallel contact surface and a 6 mm material thickness necessary for the procedure.

The low load Vickers hardness tester ZHV30 conducts Knoop and Vickers hardness tests in accordance to the ISO6507, ISO4545 & ASTM E 384.The test load range is between HV0.2 and HV30. With an an automatic 5 position turret for an indenter it consists of maximum of 4 lenses facilitating the change and selection through the menu buttons. The magnifications of 25x to 500x helps in covering various applications. Integrated microscope and front panel display facilitates quick and easy hardness testing. The dwell times may be easily configured in electronics and test cycle is automatic. The load change is automatic and the test load is selected through the operating panel. Illumination intensity for each magnification lens can be stored individually. PC controlled versions,based on a High Definition software, which are semi automated or fully automated are also available for automated and sophisticated applications.

The HT1000 and HT2000 have many applications in the primary metals, metal fabrication, utilities, petroleum, chemical, automotive and aerospace industries. Their small size and easy to use, one-handed operation, makes them ideal for testing large and heavy forgings or castings, such as steel mill rolls and turbine housings. Due to their small size and portability, the testers can be used to test individual parts of a large assembly without taking the finished assembly apart. The testers can be used in any direction, and require only a small surface area to obtain a quick and accurate reading.

The ZHU/Z2.5 is the most versatile and flexible hardness testing machine in the world, it has a zwickiLine testing machine with a hardness measurement head which contains a digital travel-measuring system and an exchangeable indenter with sensor foot. It can be used with all ZwickRoell Materials testing machines and in automated applications. All indentation depth measurement method hardness tests, including Martens hardness HM, Rockwell hardness, and ball indentation hardness can be performed. Vickers depth measurement HVT, Brinell depth measurement HBT, and Knoop tests can be performed with an optical unit accessory attached to the head. This unit contains a measuring microscope and a linear displacement component, which allows the microscope and load unit to exchange positions without the need to move any components under test.
