iqualitrol Operation Manual Rockwell Hardness Tester
Brief Introduction:
1, iqualitrol HRMS-45 digital Rockwell hardness tester has a novel
appearance, measuring device using a grating sensor and a computer
control.
The hardness indication value directly display on the liquid
crystal screen as an electromechanical hardness tester.
2, iqualitrol HRMS-45 Rockwell Superficial hardness test method
consists of indenting the test material with a diamond cone (N
scale) or hardened steel ball indenter. The indenter is forced into
the test material under a preliminary minor load usually 3 kgf.
3, iqualitrol HRMS-45 can carry out automatic conversion of various
hardness scales, identify the minimum thickness parameters of the
test pieces to automatically convert each other, identify the
minimum thickness of the test piece and determine the ambient
temperature of the test.
4, iqualitrol HRMS-45 with the features of easy operation, tiny
indentation and high precision, Built-in printer reads relevant
test results. Automated operation eliminates manual operation and
reading errors.

Main Functions and Features:
1. Directly display the test hardness value through the large LCD
screen;
2. The shell is made by a special sandblasting process with a
one-step casting process. The structure is stable without
deformation and can work in a relatively harsh environment. The car
has a high-grade paint and a strong anti-scratch ability. It is
still bright as a new product for many years.
Application:
Rockwell superficial scales are used to test materials too thin or
small for the regular scales or outside the regular ranges.
Generally Diamond Indenters are used for hard materials while Ball
Indenters are used on soft materials, like Surface hardened steel,
copper, aluminum alloy sheet, strip steel, hard alloy steel;
The HR 15 N scale is useful for testing hard thermal spray coatings
like ceramics and carbides, while at the other extreme the HR 15 Y
scale is used to test very soft abradable coatings, Galvanized,
chrome plated, tin plated, surface heat treated and chemical
surface treated metal materials.
