Model THL-3000 Portable Leeb hardness test equipment

Application &Feature:

Model THL-3000 leeb hardness test quipment is based on a physical principle of dynamic hardness testing. By spring force with the impact of the hard metal body into the head surface of the specimen. When testing the impact of body surface will impact the surface deformation, which will result in the loss of kinetic energy. Permanent magnet within the impact body position at impact to produce a single-coil induced voltage. The voltage signal proportional to the velocity of the impact body, after the signal processing electronics provides the hardness reading for display and storage.

1. LCD backlit display, easy reading
2. Precision ± 4HLD (800HLD pm)
3. Automatic correction for impact direction according to
4. Conversion to all common hardness scale (HB, HV, HRB, HRC, HS, σb)
5. Lightweight chassis, shock-proof solid
6. Rapid detection, wide range of applications
7. Large-capacity memory can be downloaded directly via RS-232 to a computer or printer to view the data
8. Standard AAA batteries
9. Sensor using Swiss technology, Swiss imports of tungsten top ball hardness 1900HV, far exceeding the requirements of the three highest standard 1600HV, wear almost zero
10. Far more than 300,000 times a fatigue test to ensure the quality and precision instruments
