Principle of leeb hardness tester
Publish Time: 2018-04-10 Origin: Site
The Leeb hardness tester is a kind of test equipment. The principle is based on the development of the monolithic technology in 1978, Dr. Leeb of Switzerland proposed a new method of hard testing for the first time. Its basic principle effects body with a high quality. Impacting the surface of the specimen under a certain test force, measuring the impact velocity and rebound velocity of the hardness meter away from the surface of the specimen, and use the electromagnetic principle to sense the voltage proportional to the velocity.
Application：
Machine tool guideways, Hardness Testing of Automotive Chassis
Installed mechanical or permanent assembly parts
Mold cavity and other test space with very narrow workpieces
Rapid inspection of large-scale workpieces at multiple locations
Failure analysis of pressure vessels, turbine generators and other equipment
Bearings and other parts production lines
Material division of metal material shore hardness tester
Heat treatment by workpiece quality control
Requiring a formal and original record of paint hardness test
It can realize the mutual conversion between six kinds of shore durometer
(HL, HRB, HRC, HB, HV, HS) and the conversion between hardness and tensile strength. It can display the measured value, average value, impact direction, test times, hardness system and other information. , Showing rich information.
Features：
Six types of hardness (HL, HRC, HRB, HB, HV, HS) can be converted to each other.
The test results can be displayed repeatedly, and digital ultrasonic hardness tester
can be deleted.Can store 50 sets of measurement values and test status, including materials, test direction, hardness and other information.
Allows users to calibrate to make measurements more accurate.
With RS232 interface, easy to communicate with the computer.
Backlit display, easy to use in low light conditions.
Manual and automatic shutdown.
Low battery voltage indication.
