SL-140 Portable Digital Leeb Hardness Tester Multifunction Hardness Tester LCD Dis-Play High Precision for Hardness Testing of Precious Metals

Digital Lee-b hardness tester is developed Leeb hardness measurement principle based on the internationally popular metal material hardness tester. It has high accuracy,small size,easy to operate and a wide range of measurement,especially for large,heavy-duty malleable pieces, example: roll turbine shaft and applied to the components already installed and can not be demolished, for example:site hardness testing of pressure vessels, turbine units and other equipment. Leeb hardness tester is widely used in petrochemical, aerospace, electric power, gas, automotive, shipbuilding, railways,machinery manufacturing and other industries. 6.Requires a formal original record of the test results. 7.Material distinction of metal materials. 8.Rapid test of multiple measurement sites in large scale workpiece. 9.Working temperature: －10℃～＋55℃; 10.Storage temperature: －20℃～＋75℃; 11.The relative humidity is less than 90%; 12.There is no vibration, no strong magnetic field, no corrosive medium and serious dust in the surrounding environment. 13.Based on the principle of measuring the Leeb hardness, it can be measured in a variety of metal materials. 14.Easily switch to the hardness of all formats (HL、HB、HRB、HRC、HRA、HV、HS), parallel conversion of the measured value of the hardness 15.Using the big screen 128 x 64 graphics dot matrix LCD disp-lay, information is rich, intuitive. 16.With bright backlight disp-lay, easy to use in the light gray environment. 17.A host can be equipped with 7 kinds of different impact device, automatic identification of impact device type. No need to re calibrate the replacement.

• 1.Installed mechanical or permanent assembly parts.
