Functions of the Phase II PHT-2000 Hardness Tester
Phase II PHT-2000 is an advanced, integrated hardness tester that provides high accuracy
and simplicity of operation throughout a wide measuring range. It is suitable for testing
the hardness of ordinary metals and is widely applied in many industries including the
petroleum, chemical, industrial machining and electric power industries, etc.
2.1 Typical
Applications
Typical hardness testing applications of the PHT-2000 include:
•
Inspection of installed machinery, permanent parts of assembled systems and heavy
workpieces
•
Inspection of the moulding surface of a die
•
Analysis of pressure vessels, turbo generator sets, etc.
•
Inspection of bearing and other mass produced parts on a production line
•
Obtaining original records of test data
