1. Introduction
PCE-2000 is an advanced Hand-held hardness tester, characterized by its high accuracy, wide measuring
range and simplicity for operation. It is suitable for testing hardness of the ordinary metal and widely applied in
many industrial fields, such as petroleum, chemistry machinery and electric power industries et c.
2. Typical Applications
Installed machines and permanent parts of assembled system
Molding surface of die
Heavy work-pieces
Ineffectiveness analysis of pressure-vessel, turbo-generator set etc.
Bearing and other messy produced parts at production line
Obtaining test data requested as original formal records
Identifying metallic material stored in a warehouse

6. Pretreatment of Samples
6.1. Pre-treatment of Samples Surface
To eliminate hardness error possibly resulted from the roughness of sample surface, the test surface should be
polished smooth, neat appearing metallic luster until its roughness Ra attends no more than 2um. The test
surface should be clean and free from oil stain.
6.2. Support to test samples
For test samples weight over 5kg, no support is needed.
Samples of cantilever or thin shell shape and weight over 5kg to be coupled firmly and tightly with them so as
to prevent themselves from bending deformation or displacement due to impact force.
Test sample weight less than 2kg should be coupled grimly and tightly with support weight over 5kg
Minimum weight of a test sample should not be less than 100g, minimum thickness not less than 5 mm and
minimum depth of hardened layer, not less than 0.8mm.
6.3. Advice
When the test sample is a large plate, long bar or bent work piece, impact force can cause it deformed or
unstable and bring about error in measurement even if its weight or thickness seems applicable. In this case
reinforcement should be bound to the back of the sample surface opposite to the impact force.
6.4. Test sample should not be magnetic in property.
