HRMS-45 Digital Surface Rockwell Hardness Tester
HRMS-45 digital surface Rockwell hardness tester is a relatively
advanced surface Rockwell hardness tester that adopts a large
screen display and operation to display the hardness value
digitally. Through the touch operation of the large screen, the
surface Rockwell hardness scale can be selected, the test data can
be displayed digitally, and the conversion between various hardness
values can be performed. And it has the functions of test data
storage, printout, RS-232 super terminal setting, etc. The machine
has good stability and intuitiveness.

Surface hardened steel, material surface heat treatment and
chemical treatment, copper, aluminum alloy and other thin plates,
galvanized, chrome-plated, tin-plated materials, bearing steel,
chilled castings, etc.

1. How do you perform a hardness test?
A hardness test is typically performed by pressing a specifically
dimensioned and loaded object (indenter) into the surface of the
material you are testing. The hardness is determined by measuring
the depth of indenter penetration or by measuring the size of the
impression left by an indenter.
2. How do I find my Rockwell hardness number?
The Rockwell hardness number is calculated from the depth of
permanent deformation of the indenter into the sample, i.e. the
difference in indenter position before and after application of the
major load. The minor and major loads can be applied using dead
weights or springs.
3. How ofen should a durometer be calibrated?
one year
Unless otherwise requested the calibration interval on your
durometer will be one year. Several factors should be taken into
consideration such as: the required accuracy vs. the instruments
accuracy, the impact an out of tolerance reading will have on the
process, and the performance history.
