Mitech MHRS-150T Cantilever Rockwell Hardness Tester

Overview

Mitech MHRS-150T Cantilever Rockwell Hardness Tester, also known as convex nose dual Rockwell hardness, based on the mechanical principle of conical diamond or hard alloy indenter pressing into the sample surface to produce indentation, realizing the material hardness measurement by measuring the depth of the indentation. With novel appearance, stable performance, touch screen operation easy and real-time monitoring test environment temperature, it can solve the problem of ring, tube, groove type workpiece surface, convex workpiece surface while other general Rockwell hardness tester can not measure the workpiece Rockwell hardness testing requirements. it is widely used in metal processing and manufacturing, various metal material’s failure analysis and other fields like colleges and research institutions, and it is the precise and high-tech equipment to test the metal materials Rockwell hardness.

Technical Parameters

Indication error

Features

• Widely used in the ring, tube, groove type workpiece surface, it can test the convex parts of the workpiece and the workpiece Rockwell hardness and surface Rockwell hardness that other general Rockwell hardness tester can not measure;

• Adopt large-screen LCD, easy to operate, visually display the test results;

• Equipped with excellent performance of cemented carbide or diamond indenter, high hardness, wear resistance, good toughness, with high temperature, corrosion resistance, to ensure that the instrument test value is accurate, stable and reliable;
• With the function of error value correction, the hardness value of the error can be automatically modified by key input, easier to meet the test accuracy requirements;
• Support the conversion among various hardness scales such as Brinell, Vickers and etc;
• With the function of threshold overrun automatic alarm, which applies to the bulk of finished products or semi-finished pieces of paper-by-piece detection;
• Option for various specifications of the indenter, support 15 types of Rockwell hardness scales testing;
• The function of original ambient temperature real-time display can avoid the instrument working in the case of high or low temperature for a long time , resulting in increased test error and reducing the service life;
• Equipped with high-speed thermal printer, real-time print test results;
• Consistent with EN-ISO-6508,GB/T230.1,GB/T230.2,JJG112,ASTM E18 and other relevant standards at home and abroad.

The Scope of Application

Note: A, B, C are the commonly used test scales for Rockwell hardness test.

Note: The surface Rockwell hardness test commonly use the N and T two scales.

Applications

• Used for quality control in metal processing manufacturing
• Used for failure analysis testing of metallic materials;
• Demonstration experiment for education and teaching in Colleges and Universities;
• Hardness testing of materials in scientific research institutions

Working Conditions

• Operation Temperature:10～30℃；
• Relative Humidity:≤65％；
• The surrounding environment should avoid of vibration, strong magnetic field, corrosive medium and heavy dust.

Configurations

Maintenance and Precautions

• The test personnel should follow the operating procedures.Before and after the test,it should be repeated with standard block calibration equipment;
• The hardness value needs to be corrected when the measured surface specimen is less than 38 (25) mm.
• If the specimen has visible deformation marks on the back and edges, the test result would be useless. It should choose the intender or test force to test again;
• Normally, the first point is only used to offset the gap of each support surface without needing to record the test result. Record the statistical test result from the second point;
• During testing, to ensure accuracy, please make sure the distance between the adjacent indentation center and the distance from the indentation center to edge of the specimen is greater than 3mm;
• Pay attention to palm the instrument for carrying to forbid falling across. Please fix well the measuring lever, counterweight and boom before carrying;
• It is strictly prohibited to turn the variable loading handwheel when the instrument load or unload the test force. Rotating the handwheel forcibly will cause the internal gear dislocation, test force in chaos and even damage the internal parts of the instrument;
• Turn off the power after using the instrument;
• When not in use for a long time, please cover the dust cover to prevent dust into the instrument interior. And the hardness block, indenter should be coated with antirust oil to prevent rusting after using;
• Long time after the re-enabled,it should be preheated the electrical components before test
• The hardness tester should be calibrated at least once a year to ensure its accuracy;
• Don’t disassemble the instrument without authorization, for maintenance related matters, please contact MITECH after-sale service department with 4000600280.
