HLM-100 Plus - Fully Equipped Digital Leeb's Hardness Tester

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.

 

• 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-line 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 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.

• Intelligent battery recharge management.

• Pre-Loaded Material Codes:
  Steel, Cast steel, Alloy Tool Steel, Grey Cast Iron, Nodular Cast Iron, Aluminium Alloys, Brass, Bronze, Copper alloys

• Strength testing Conversion for steel and cast steel.
