2、 Product Introduction

Hardness is one of the important indicators of material mechanical properties, and hardness testing is an important means of judging the quality of metal materials or parts. This hardness tester uses displacement transmissionSensors and photoelectric encoders are measured and processed by an internal microcomputer system before being processed4.8 "large screen LCDDisplaying mid to high end products that canOutput through printer. Due to the correlation between the hardness of metals and other mechanical properties, most metal materials can be approximately calculated for other mechanical properties such as strength, fatigue, creep, and wear by measuring hardness.

3、 Product principle

The digital Blowe hardness tester has three testing methods: Brinell, Rockwell, and Vickers, and is a multifunctional hardness tester with seven levels of testing force, which can meet various hardness testing needs. The loading, holding, and unloading of the test force are achieved through an automatic switching mechanism. The transformation of the test force is obtained by the rotation of the handwheel, and the indentation is measured by a high-precision encoder and sensor. The hardness value is calculated and displayed by the internal system program. So the operation is simple and fast, the interface is intuitive, there is basically no human error in operation, it has high sensitivity and stability, and is suitable for workshops and laboratories.
