Hardness Tester,Newest Magnetic Type Rockwell Hardness Tester

Detailed Product Description

Features

 

Attracted to iron or steel surface by magnetic force; only one side of the workpiece needs to be reached.

The test principle and accuracy comply to standard ISO6508 and ASTM E110. Tested by ational Institute of Metrology with tolorance 1.5HRC, equivalent to bench hardness tester.

Quick test, easy operation, good repeatability, high accuracy, no sampling required.

Tests workpieces of any shape and dimension only if there is enough flat or cylindrical surface to fix the tester.

Tests horizontally, slantingly and vertically.

Used to accurately test the hardness of steel plate, steel pipe, shaft, mould, tube, pressure vessel, large workpieces and assembled parts, especially welding line and heat affected zone.

The test surface of PHR-100x is small enough to test the hardness of small machine guide rails.

Used for production inspection and acceptance inspection, replacing Leeb hardness testers with lower precision.

Traceable standard hardness block.

Indenter inspected with standard Rockwell hardness tester.

Test force calibrated with load cells directly traceable to national secondary benchmark.

 

Application

 

The test is quick, easy and steady with good repeatability and accuracy. So when the workpiece is available magnetic type hardness tester is the best choice.

Magnetic type superficial Rockwell hardness tester is under development to test smaller, lighter, thinner specimens such as thin plate, thin hard carburized and nitrided steel.
