Rockwell Hardness Testers

首页 » Rockwell Hardness Testers
Model: 
HR Series

Designed to test the hardness value of various materials according to Rockwell Principles.

These units measure the depth difference between the primary and testing load and convert the depth difference to the hardness value. Machines can be operated semi-automatically.

Model HR-150A - Rockwell tests, scales A-B-C. (60/100/150kgf) with dial indicator and hand control loading.

Model HR-150DT - Rockwell test with scales A-B-C (60/100/150kgf ) with dial indicator and motor control loading.

Model HRS-150 - Rockwell test with scales A-B-C (60/100/150kgf ) with digital indicator and motor control loading. Hardness value converts to HV, HB.

Model HRM-45 - Superficial Rockwell test scales N & T (15/30/45kgf) with dial indicator and hand control loading.

Model HRM-45DT - Superficial Rockwell test scales N & T (15/30/45kgf) with dial indicator and motor control loading.

Model HRMS-45 - Superficial Rockwell test scales N & T (15/30/45kgf) with digital indicator and motor control loading. Hardness value converst to HRA, HRB, HRC, HV, HB

Model XHR-150 - Tests plastic hardness according to ISO 2039-2 and ASTM D785. Its test scales include HRR. HRL, HRM, HRE,HRK with dial indicator and motor control loading.
