Electronic Digital Display Rockwell Hardness Tester for Metal
Product Description
1. We are Manufacturer, selling our produces.
2.Give you Reasonable price.
3.The Fastest delivery for urgent orders.
4. Guaranteed goods high precision and stability
5. Provide our customers 2 year after sales service.
Introductions:
Special designed for improving the working efficiency of our
customers as its automatically design. After adjusting the focal
length, the objective lens and indenter can be switched
automatically. And the testing force can load, dwell and unload
automatically. Then the objective lens will automatically return to
the initial focus state, and the length of indentation can be
measured directly.
Features:
1. Operational panel is concise and clear with menu structure, and
with English and Chinese interface, easy switching.
2. The hardness values, diagonal length, dwell time, testing
frequency, environmental temperature, the maximum /minimum value of
test, average value and repeatability can be displayed directly.
3. The testing data able to be printed directly by the built-in
printer.
4. Can be connected with computer, used the image analysis software
to analyzing the physical and chemical properties of the material.
Main purpose and the scope of the application:
1. Ferrous metals, non-ferrous metals, castings and alloy
materials.
2. Heat treatment and carbonation specimen, quenching and mini
parts which with miscellaneous point.
3. Applicable to the Knoop hardness test of glass, ceramic, agate,
precious stones and other non-metallic hard but brittle materials.
