Introduction
Our advanced Macro Vickers hardness tester 900‐398 is a state‐of‐the‐art, precise testing system suitable for
hardness analysis of metallic specimens in metallography laboratories or production environments.
Designed for the accurate hardness testing of small precision parts, thin materials, case hardened layers and all
sorts of steel components. The Phase II 900‐398 is our macro‐vickers hardness tester, covering the load range
from 1kg to 50kg, with digital technology. Conforming to ASTM E‐384/92 vickers hardness testers standards, the
900‐398 digital vickers hardness tester will offer unmatched repeatability. A perfect rugged performer suited for
any environment, the Phase II vickers hardness testers are offered with a 5 year warranty and free lifetime
technical support.
The 900‐398 Vickers Hardness Tester is engineered to produce a clear indentation and a more precise
measurement. By means of a load cell, closed circuit system for control, the CPU controls testing force to
load/dwell/unload, allowing for the highest degree of accuracy. The large LCD shows the measuring methods, the
testing force, the indentation length, hardness value, the dwell time of the testing force as well as the number of
the measurement on its screen. All information such as diagonal lines length of indentation, hardness values, data
statistics and hardness conversions can be displayed on the LCD.
The tester can be adapted with a ccd camera for operation and data control via pc.
