PHR-200 Digital Magnetic Rockwell Hardness Tester

PHR-200 Digital Magnetic Rockwell Hardness Tester

World leading product designed and manufactured by TX company with patent, because of high-accuracy sensor and unique distance measuring technology, reaching far higher test accuracy than other portable hardness testers. It is fixed onto the surface of a iron and steel part smartly with magnetic chucks. This digital Rockwell hardness tester follows the Rockwell hardness test principle, and complies with relevant regulations of ISO6508, and ASTM E18 standards.
The digital portable hardness tester is mainly applied to test too large or heavy iron and steel parts for the desk testers.
This digital hardness tester is also used to test the hardness of steel parts, bearings, moulds; large and medium-sized heating parts.

Features of PHR-200 Digital Magnetic Rockwell Hardness Tester

High Reliability
1                        High Reliability                        With advanced imported sensors as well as high integration, high stability electronic components to keep the high reliability of the hardness tester.                    
Wide Test Range
2                        Wide Test Range                        Test by absorbing to iron and steel parts, and it can finish the test by unilaterally touching the parts. It can test any dimension parts, especially steel tubes and weld on pipes.Test a large batch of parts piece by piece on site.                    
Design of Light
3                        Design of Light                        Test point with lighting, convenient to observe the test processing.                    
Digital Display Function
4                        Digital Display Function                        Adopt digital display technology to show test force and other information on LED display of hardness tester, it is convenient to operate.                    
Traceable Calibrated Block
5                        Traceable Calibrated Block                        It permits customer to calibrate the tester with a standard block at any time.
