summary:

The hardness tester is a bench Rockwell hardness tester, which adopts Rockwell measurement principle and is used for hardness testing of carbon steel, alloy steel, cast iron, non-ferrous metals, engineering plastics and other materials. It has the characteristics of high test accuracy, wide measurement range, automatic loading and unloading of main test force, digital display and automatic printing of measurement results or communication with external computers. It is widely used in measurement, machinery manufacturing, metallurgy, chemical industry, building materials and other industries for testing, scientific research and production.

Features: 1. Accurate measurement, simple operation, easy to carry and beautiful appearance

2. With peak latch, average value calculation and undervoltage alarm functions

3. Capable of data communication with computer

4. Connected with fixed load frame for high-precision stable measurement

5. Product application with user self calibration function
