Model overview

HRSS – 45A digital ROCKWELL hardness tester set all ROCKWELL, superficial ROCKWELL, plastics ROCKWELL can work more hardness tester, using ROCKWELL (ROCKWELL) measuring principle, can be directly for ROCKWELL, superficial ROCKWELL, plastics ROCKWELL hardness measurement.Suitable for carbon steel, alloy steel, cast iron, non-ferrous metal and engineering plastic material such as hardness testing, with high measurement precision, wide measuring range, automatic unloading the main test force, measure the digital display and automatic printing or with external computer communication, etc.Can be widely used in the measurement, machinery manufacturing, chemical industry, building materials and other industries testing, research and production.

HR-45A Rockwell Hardness Tester

Product features

The body part of the product is molded by casting process and has been treated for a long time.Compared with the jigging process, the long-term use of the shape variable is very small, and can be effectively adapted to various harsh environments;

Car paint, high quality paint, strong resistance to scratch, use many years still bright as new;

The core parts are fully CNC machine parts, and the precision and stability of the machine are greatly improved.

The hardness tester has 8-inch touch screen display and STM32 single chip microcomputer control system, which can realize man-machine dialogue and automatic operation.It has high test precision, simple operation, high sensitivity, easy to use and stable indicator.

Electronic closed-loop control exerts experimental force;The application of test force, unloading and hardness value are fully realized.

STM32 has the advantage of high frequency, fast and suitable for large amount of data processing and storage, fast refresh LCD interface, system anti-interference ability compared with C51 system more stable, more reliable, error probability is low, the biggest advantage of STM32 embedded operating system, unstable dead when systems affected by external interference, able to handle errors;

The built-in test software can compensate for the hardness of the machine, so that the adjustment of the micro-deviation can not be used to open the machine cover for mechanical adjustment, reducing the use and after-sales service cost.

It can be automatically converted to the hardness value of other ruler according to the measured rockwell hardness value, and no longer need to waste time and energy to query the tedious hardness comparison table;

Built-in printer to read relevant test results.Automatic operation is realized to eliminate manual operation and reading error.

The accuracy is in accordance with GB/T230.2, iso6508-2 and ASTM E18.

Range of application

Determination of rockwell hardness of ferrous metals, nonferrous metals and non-metallic materials.

Determination of plastics. Hardness of composite materials and various friction materials and soft metals, non-metallic materials, etc.

Determination of surface rockwell hardness of black metal, alloy steel, hard alloy and metal surface treatment (carburizing, nitriding, electroplating layer).
