Manual Loading Digital Display Rockwell Hardness Testing Machine
with Scales Conversion
Model: HR-150AS
Brief Introduction:
Rockwell hardness test is an empirical indentation hardness test
that can provide useful information about metallic materials. This
information may correlate to tensile strength, wear resistance,
ductility, and other physical characteristics of metallic
materials, and may be useful in quality control and selection of
materials.
The manual Rockwell hardness tester has stable and reliable
performance and is a popular type Rockwell machine.
Mechanical manual test, no power;
Wide application scope, easy operation, good economy and
practicality.
Main Functions and Features:
1. Read the hardness value directly through the digital display
screen with a resolution of 0.1. The measured result is higher than
the national standard;
2, can be directly HV, HB hardness unit conversion;
3, low power consumption, long use, digital display head CR2450
battery power;
4, with time display function;
5, with data output function, can be an external computer or serial
micro-printer;
6. The shell is made by a special sandblasting process with a
one-step casting process. The structure is stable and not deformed.
It can work in a relatively harsh environment. The grade of
automobile paint is high, and the scratch resistance is strong. It
is still bright as a new product for many years.
7. We have our own R&D, production and processing capabilities.
Our machines provide parts replacement and maintenance upgrades for
life.
Main Application:
1. Quenched steel, quenched and tempered steel, annealed steel,
bearing steel, strip steel, hardened steel sheet, hard alloy, etc.;
