Product Description:
Digital Leeb 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.
Product features
1.Based on the principle of measuring the Leeb hardness, it can be measured in a variety of metal materials.
2.Easily switch to the hardness of all formats (HL,HB,HRB,HRC,HRA,HV,HS), parallel conversion of the measured value of the hardness
3.Using the big screen 128 x 64 graphics dot matrix LCD display, information is rich, intuitive.
4.With bright backlight display, easy to use in the light gray environment.
5.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.
Main application
1.Installed mechanical or permanent assembly parts.
2.Heavy work piece.
3.Invalidation analysis of pressure vessel, steam turbine generator set and its equipment.
4.Test space is very narrow artifacts
5.Bearings and other parts.
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.

Alarm output The upper and lower limits of the hardness value can be set in advance, and the alarm will be automatically alarmed when the range is exceeded, which is convenient for users to test in batches.
Calibration With indication software calibration function.
Battery The power supply adopts 2 AA (No. 5) ordinary alkaline batteries, which can work continuously for no less than 100 hours. It has power-saving functions such as automatic sleep and automatic shutdown.
Product Description
HR-150A double handle type is another fundamental model of all rockwell types,it is favored by most customers mainly because of its mechanical and manual testing mode,which is durable and stable.Without electrical power supply,and with simple designed appearance and single handle,it is very easy to operate,as well as economical and practical performance and wide using scope.There is no parameter distinguish between single and double handle type,it only depends on the user's operation habit and personal hobby.
Using Scopes:
● Rockwell Hardness Testing of Ferrous Metal,Non-ferrous Metalt and Non-metallic Material.
● Hardened and surface hardened steel, hardening and tempering steel, tempered steel, cold and hard casting parts, forging parts, hard alloy steel, aluminum alloy,bearing steel, carburized steel sheet, etc.
Feature:
● Easy to use, and the test force can be applied and unloaded by a handle;
● Dial direct reading, HRA, HRB, HRC scale;
● Other scales of Rockwell are optional;
● High precision of indication, easy installation and low failure rate
