Model: HLM-100Plus Portable Hardness Tester
The HLM-100 plus hand-held digital
hardness tester features high
measuring accuracy, reliability and
durability, wide measurable hardness
ranges, ease of operation, and
portability (light weight and small
dimensions). HLM-100 plus comes
with a powerful built-in
microprocessor, a convenient mini-
printer, and a RS-232C
communication port (all are standard
features). This hardness tester has
been widely used in a long array of
industrial sectors.


Why HLM-100 Plus Multifunctional Hardness Tester?
- Convenient hardness measurements at difficult-to-access locations or in confined spaces such as
  the inner wall surface of a die or mould;
- Determination of hardness variations over a large surface area;
- Hardness testing on heavy and large work pieces or on permanently installed parts or machines
  whose hardness cannot be measured by using a traditional hardness tester;
- In-Iine hardness measurements essentially in real time during the manufacturing process.



■ Highlighted Features
- Automatic conversion between different hardness scales: Correlations between HL values and other
standard hardness Values (Brinell, Vickers, Rockwell and Shore) have been established for 9 most
commonly used materials. Conversions between different scales can be readily accomplished.
- Measurements can be made from several different directions: This feature makes it convenient to conduct
hardness measurements on a large part or within a confined space.
- The measuring accuracy may be compromised if erroneous data with an abnormally large deviation are
accepted. The instrument provides a manual error-correcting deleting function during batch test situations.
- High batch testing efficiency: For a batch test that involves testing a large number of similar parts, the
expected range of hardness values can be pre-set based on different requirements for improved testing

                                                     19
efficiency. Upper or lower hardness limits can be pre-set for material sorting.
- Data printing functions: Data acquired may be
printed out immediately or stored and printed at a later
time.
- RS-232C Communication port: Transfer data to a PC
for further data reduction and processing.
- Automatic power-off: When the tester remains idle
for 4 minutes (no measurement made and no key-pad
pressing operation) or when battery power is below a
critical level, tester power will be automatically
switched off.
- Auto Re-set: During power-up and power-down, the
tester is capable of automatic re-setting.
- LCD backlit by advance Electro-Luminescence (EL)
technology:     Liquid     crystal   display   with   back-
illuminating capability.
