Huayin Test Instrument
Summary:
Professional R & D and production of metal, non-metallic materials hardness tester
Main features:
● Electronic loading,closed-loop control of test force;
● Clear and intuitive display,stable and reliable performance;
● ARM high-speed processor and 8-inch LCD touch screen are adopted,providing convenient interface operation;
● Can be displayed current test scale,test force,holding time,hardness conversion value,indenter type,etc.;
● The loading,dwelling and unloading of test force are automatically performed;
● Automatic compensation of test force,high force accuracy;automatic correction of convex hardness value;
● With software calibration function;the test process dynamically displays the displacement-force curve for easy observation and analysis;
● It can set the upper and lower limits of hardness testing,and the buzzer will automatically indicate when the hardness exceeds the limit;
● The unique design of the screw self-locking mechanism automatically locks the screw and handwheel after the preload is applied,automatically applying the test force,eliminating human error and improving measurement accuracy;
● 15 types of superficial Rockwell hardness scales;Chinese and English language interface conversion;various hardness value conversions;
● Equipped with USB and RS232 data interfaces,allowing users to easily process data;
● With database storage data function,test data is synchronized and exported;
● Equipped with a micro printer,it can directly print the hardness test results;
● An optional upper computer system can be used for data uploading and intelligent control operations;
● Accuracy complies with GB/T 230.2,ISO 6508-2 and ASTM E18
Application range:
● Determining the superficial Rockwell hardness of soft metal materials such as ferrous and non-ferrous metals;
● To measure the superficial Rockwell hardness of metal surface treated(carburizing,nitriding,plating,etc.);
● Determining the superficial Rockwell hardness of quenching,tempering and other heat treatment materials;
● Determining the superficial Rockwell hardness of high-hardness alloy materials such as cemented carbides;
● It is used to measure the superficial Rockwell hardness of certain non-metallic materials such as plastics and cardboard.
