| | | Vickers Hardness Testers Vickers Hardness Testers Zwick/ZHV1 m, Zwick/ZHV2m The manual micro-Vickers hardness tester is compliant with the international standards ISO 6507 and ASTM E92. The tester is available in two upgrade stages. The ZHVIm has test load steps (manual load change): 10, 25, 50, 100, 200, 300, 500, 1000 gf and the ZHV2m has load steps: 25, 50, 100, 200, 300, 500, 1000, and 2000 gf. The tester is equipped with an automatic revolving head for changing between intruder and objective lens. Standard equipment includes a compound table as well as a high-precision vise and other accessories. | | | Universal Hardness Tester Zwick ZHU 250 The universal hardness tester is designed for a load (closed-loop system) up to 250 kg. This machine is in compliance with international standards DIN EN ISO 6507, ASTM E92 (Vickers HV1 to HV100), ISO 4545, 4546 (Knoop HK1), DIN EN ISO 6506, ASTM E10 (Brinell HBW1I1 to HBW10I250), DIN EN ISO 6508 (Rockwell with all | | |

A master test plan includes series test to Vickers, Knoop, and Brinell. Options include upgrades for automatic indentation measurement and focusing as well as hardness sequence tests with manual or motorized compound tables. | | |
| | | In addition to numerous (statistical) functions, the tester also has a serial interface and a USB connector. These and the „Small Machine" test program allow the tester to be connected to a PC running the Zwick test software testXpert® In place of the microscope, the manual micro-Vickers hardness tester can optionally be equipped with a CCD industrial camera system for automatic indentation measurement in combination with testXpert®. | | | current scales) and is also suited for determining the ball indentation H (49 to 961 N) for plastics compliant to ISO 2039. The standard equipment for the ZHU250 includes a pressure plate. Objective lenses with various magnifications (15x to 520x) as well as various test anvils allow for a broad spectrum of applications. The serial interface and the "Small Machine" test program allow the ZHU250 to be connected to a PC running the testXpert®test software. | | |
