FEATURES:
  • Highly accurate
  • Easy to use
  • Suitable for testing a variety of materials
  • Compact and lightweight-perfect for testing materials on-site
  • User friendly monitor clearly displays test results: readings in HL, HV, HB, HRB, HRC, or HSD hardness scales;
Operation:
Operation of the HT-1000A/HT-2000A is easy and test results can be obtained in just seconds. To obtain a reading simply load the tester, position it on the material, and push the button. Setting up the instrument is also very simple. Two function keys are used to select up to 10 materials, 6 hardness scales and 5 testing directions.

Application

The HT-1000A and HT-2000A have many applications in the primary metals, metal fabrication, utilities, and petroleum, chemical, automotive and aerospace industries. Their small size and easy to use, one-handed operation makes them ideal for testing large and heavy forgings or castings, such as steel mill rolls and turbine housings. Also, due to their small size and portability, the testers can be used to test individual parts of a large assembly without taking the finished assembly apart. The testers can be used vertically or horizontally, and require only a small surface area to obtain a quick and accurate reading.

These versatile testers can be easily used by anyone, anywhere, to obtain direct accurate hardness readings.

Principle

The HT-1000A and HT-2000A hardness testers operate on the Leeb principle, a dynamic hardness test method based on velocity measurement. They include a guide tube and an impact body. The impact body contains a magnet and tungsten-carbide ball, measurements are performed using a spring to propel an impact body through a guide tube towards the test surface. When the ball is within 1 mm of the part¡¦s surface, the magnet induces a voltage into a coil surrounding the guide tube. After penetration, the impact body rebounds and the magnet returns through the coil inducing a second voltage. Both voltages are proportional to the velocity of the impact body.


¡@
Leeb hardness value (HL) is determined using the following formula:
              HL = (Vb/Va) x 1000

Where Vb is the rebound velocity of impact body and Va is the impact velocity of impact body.
