Rockwell hardness tester with magnetic base PHR series

Description

OPERATING PRINCIPLE

The PHR Rockwell series features a magnetic base allowing the user to clamp onto the surface of large iron and steel components.

Performs an authentic Rockwell hardness test in line with ISO 6508 and ASTM E18.

The portability means the user can perform on-site tests wherever the component surface is suitable and accessible.

These portable Rockwell hardness testers are an excellent replacement for a Leeb tester, offering far greater accuracy and reliability.

INSTRUMENT FEATURES

It is a portable unit which clamps magnetically to the test surface – take the tester to the component rather than the component to the tester.

Performs an authentic Rockwell hardness test.

Easy to read results.

Excellent repeatability.

Complies with ISO 6508 and ASTM E18.

The PHR-100 is a manual, analogue device where the test force is entirely user-controlled.  The tester is magnetically clamped to the component and the force is applied by means of the user turning the handle on the top of the device until the gauge shows the required pre-load.  The gauge is then ‘zeroed’ by the operator and the handle turned further until the full test force is applied.  Once the correct dwell time at full load has been achieved, the user winds back the test force until the gauge shows that the pre-load is being applied once again and the hardness value is then read from the indicator.

The PHR-200 has a digital display and allows the user to monitor the test force electronically. The means of operation is broadly similar to that of the PHR-100 with the benefit that the test time application is also displayed electronically giving the user the opportunity for more reliable test cycle times.  Also, the result is displayed digitally at greater resolution than the PHR-100.
