PHR-100 magnetic type Rockwell hardness
* sucker will use magnetic hardness fixed in the steel surface, no support, no sampling, no mobile
workpiece, as long as the contacts to complete the test side.
* and desktop the same experimental principle and the accuracy standard GB/T230, ISO6508 and ASTM
E110, detected by the Institute of Metrology, the error is not greater than 1.5HR.
* test is rapid, simple, non-destructive.
* such as micrometer readings of the same drum body, easy reading, good repeatability and high accuracy.
* with a magnifying glass with light to ensure that when used in dark reading workshop more convenient.
* can test plane and the curvature of the workpiece to infinity from
