Portable Rockwell Hardness Tester Accurate for Metal Materials HARTIP3210

HARTIP 3210 is a new generation of hardness tester with more advanced technology and features. The tester applies our new patent technology which makes the tester more accurate than old previous model. All impact device (probe) are no need to setup impact direction. HARTIP 3210can work with both analogy impact device and wireless RF probe.

The measuring values can be downloaded to PC and printer by wireless or by cable.

The HARTIP3210 also can be powered by USB power supply without battery via PC cable.

MEASURING METHOD

The measuring principle of HARTIP series hardness testers is defined as "the quotient of the impact body's rebound and impact velocity, multiplied by 1000." An impact body with a Tungsten Carbide test tip is propelled by spring force against the test surface and then rebounds back. A permanent magnet is contained within the impact body. When it passes through the coil on impact device, it induces an electric voltage which is proportional to the velocity of the impact body.

Specifications

Requirements related to sample weight

• For samples weighing over 5 kg and of compact shape, no support is needed.
• Samples weighing between 2-5 kg, and also for heavier samples with protruding parts or thin walls, should be placed on a solid support in such a manner that they do not bend or move by the impact force.
• Samples weighing less than 2 kg should be firmly coupled with a stable support weighing over 5 kg.
• For coupling purposes,
  • The coupling surface between the sample and base plate should be flat, plane parallel and ground.
  • A proper thin layer of coupling paste is to be applied to the contact surface of the sample.
  • The sample should be firmly pressed against the base plate surface by moving it with a circular motion.
  • The direction of impact should be perpendicular to the coupling surface.
• For the coupling operation, the following prerequisites must be fulfilled:
  • Contact surface between the sample and the base plate must be flat, plane parallel and ground.
  • The direction of the test impact must be perpendicular to the coupled surface.
  • Minimum thickness of the sample for coupling under various impact devices are shown in following table:
