1. Ultrasonic hardness tester HRT-6
OVERVIEW
OVERVIEW
Production of HRZ-6B intelligent nondestructive ultrasonic hardness tester is a measuring
rod by means of ultrasonic sensors to measure the hardness of a high-tech, intelligent new tool. As the instrument uses an advanced sensor systems and
micro controller technology, so the instrument in the function and structure is completely
different from the traditional ultrasonic hardness tester, especially in the realization of
Brinell, Rockwell, multi-dimensional standard hardness conversion, multi-point equilibrium value The calculation shows that the exact precision, the use of simple
procedures and many other aspects have been further refined and improved,
The instrument is mainly used in Rockwell hardness measurement can also be
converted to the corresponding Brinell, Vickers hardness to display.

Features: No damage on the surface of the workpiece, high speed, simple operation
and high precision. The finished piece, metal sheet, metal sheet (including the nitrided
layer, carburized layer, plating layer, etc. ), as well as easy movement of large parts and
difficult to remove the special shape of parts and components, can be 100% directly
hardness measurement.

THE BASIC PRINCIPLES
A uniform contact pressure, the sensor bar to the top of the pressure head and the
specimen surface contact, the hardness of specimens of different rods produced by
the resistance of the sensor is different from feedback received ultrasound signal
change. Ultrasonic hardness testing method is through receiving different ultrasonic
sensors to measure the frequency change the hardness of the specimen surface.
The elastic modulus of specimens of different, there will be some impact,
if the same standard modulus test block can be adjusted to eliminate this effect.
