LLT-R cantilever full Rockwell hardness tester

LLT-R cantilever full Rockwell hardness tester is a bench Rockwell hardness tester. It 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 adopts advanced closed-loop sensor control technology to realize full-automatic control and hardness testing process. The loading system adopts high-precision force sensor and controller to form a closed-loop loop to realize the whole microsecond tracking and control of the loading process. It is widely used in measurement, machinery manufacturing, metallurgy, chemical industry, building materials and other industries for testing, scientific research and production.

High testing precision and wide measuring range;

Upper and lower limit setting, out of tolerance alarm;

Surface correction, automatic correction of cylindrical and spherical measurement results;

The specially designed indenter extends horizontally, which can measure the parts that cannot be measured by ordinary hardness tester, such as ring and tube, with an inner diameter of at least 15mm;

Easy to operate, any language version;

It can be used immediately after startup without installing weights and debugging;

Electric loading, closed-loop control;

The test force is automatically corrected, and the accuracy of the force value is increased by an order of magnitude

All Rockwell scales, high, medium and low hardness values are automatically corrected

Set password protection setting parameters; Keep more sample and test information
