Plastic Rockwell Hardness Tester

Plastics Rockwell hardness tester adopts the mechanism of automatic loading and unloading of the test force, the test force is regulated by the load-change hand wheel. It can select the dwell time and is very easy to use. Besides setting zero to dial, there is no man-made error. The instrument has high sensitivity and stability.

Main Application:

Suitable for hard plastics, hard rubbers, aluminum, tin, copper, soft steel, synthetic resins and fricative
materials etc.

EI-R150EP: Electric Dial Type

• The dial will display hardness value directly,
  indicator responses sensitively, show the hardness value accurately.
• Cast molding frame, stable and robust structure.
• Preliminary test force load by manual, main test force load by motor.
• Automatic Load – Dwell – Unload main test force
• Dwell time can be pre-setting (2 ~ 60s)

EI-R150TP: Digital Touch Screen

• Electric loading with weights, high precision sensor.
• Touch screen interface, easy operation.
• Automatic correction of high, medium and low hardness values.
• Built-in hardness value correction of convex cylindrical surface.
• Strong data processing function, conversion of hardness value HR, HB, HV and so on, set the qualified range, overrun alarm, sample name and other information.
• Test results can be stored, processed and printed automatically.
