Richter Hardness Tester DHT-200 DGC Metal Material Richter Hardness Tester

DHT-200

Hardness Tester

Introduction

In appearance, Deguang DHT-200 Leeb Hardness Tester is a black shell, with LCD screen, button operation, small size, easy to carry. Functionally,The DHT-200 Leeb Hardness Tester is equipped with a sensitive printer that is capable of printing measurement data in real time. Using the Leeb hardness measurement principle, the hardness of a variety of metal materials can be detected, which is convenient for detection in a variety of Operating Environments, and can freely convert a variety of hardness systems, such as HRC, HRB, HV, HS, etc., and the measurement is stable and reliable.

Principle

The hardness measurement of the DHT-200 Leeb Hardness Tester is defined as:The rebound of the impactorThe velocity is divided by the impact velocity of the impactor and multiplied by 1000. For specific metal materials (e.g. steel, aluminum, etc.), the Leeb hardness value reflects the materialThe hardness relationship of the material, and the Leeb hardness value can be converted into other statically measured hardness values (e.g. HB, HV, HRC, etc.).

Measure bow and arrow requirements

The DHT-200 Leeb Hardness Tester has the following requirements for the measurement of workpieces:

1. Surface requirements

a) The surface temperature of the measured workpiece should not be overheated< 120°C;

b) The surface roughness of the tested workpiece is 2 microns, which is equivalent to the original national standard △ 6.

c) For the test of the measured workpiece with a surface diameter of less than 30mm, a small support ring or a corresponding heterosexual support ring should be used.

2. Requirements for the weight to be measured

a) Specimens weighing more than 5kg, which do not require support;

b) Specimens weighing 2-5kg, specimens with overhangs and thin-walled specimens should be supported by objects during testing to avoid impact force causing testsdeformation, distortion and movement of parts;

c) If the weight is less than 2kg, it should be tightly coupled with the support body weighing more than 5kg, and the surface of the specimen and the coupling body should be flat and smooth.The amount of couplant (alum, oil, etc.) should not be too large, and the test direction should be perpendicular to the coupling plane.
