570HAD Digital universal hardness tester
1. Hardness is one of the important mechanic characteristics of the
material while the hardness testing is an important method to judge
the quality of the metal material or its component parts. The
hardness of the metal is correspondent to its mechanic
characteristics, and so its mechanic characteristics such as the
strength, tiredness, wriggling and wearing out can be tested out
approximately through its hardness testing.
2. Digital multi-functional hardness tester with Brinell, Rockwell,
Vickers three testing methods, multi-functional hardness tester of
seven grade test force, it can meet the needs of a variety of
hardness tests. Test force loading, dwell, unload adopted automatic
switching mechanism, test force transformation obtained by the
rotation of hand wheel, indentation measured by precision encoder
and sensor and calculated the hardness value by the internal system
program. So it is easy to operate, fast and intuitive interface,
basically, no human operation error, with its high sensitivity,
stability, it is suitable for workshops and laboratories.
The main function as follows:
2.1 Brinell, Rockwell, Vickers three testing methods；
2.2 Conversion of different hardness scales
2.3 Selection of dwell time
2.4 Modifications of time and date
Specifications of Rockwell Hardness
2.5 Output of testing results2.6 RS232 interface for optional
functions, this model can save testing results and browse testing
pages.
