Resolution 0.1HR Digital Rockwell Hardness Tester , Metal Hardness Tester 

Rockwell Plastic Hardness Tester With Printer And Hardness Conversion

Brief Introduction:

iRock-437D Digital plastics Rockwell hardness tester equips with a newly-designed large displaying screen with good reliability, excellent operation and easy reading.

It can show and set the present scale, test force, test indenter, dwell time and hardness conversion.

The main functions as follows:
1, Support all the plastics Rockwell scales;
2, Support Hardness Conversion;
3, Test results can be saved and printed out,
4, Support statistics and automatically calculate maximum, minimum and average value;
5, With RS232 interface for data transferring to computer.

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

Packing List:

The Rockwell test consists of measuring the additional depth to which a carbide ball or diamond penetrator is forced by a heavy (major) load beyond the depth of a previously applied light (minor) load (SET point).

The minor load is applied first and a SET position is established on the dial gauge or displacement sensor of the Rockwell tester. Then the major load is applied. Without moving the piece being tested, the major load is removed and, with the minor load still applied, the Rockwell hardness number is automatically indicated on the dial gauge or digital display.

The diamond penetrator is used for testing materials such as hardened steels and cemented carbides. The carbide ball penetrators, available with 1/16 inch, 1/8 inch, 1/4 inch, and 1/2 inch diameter, are used when testing materials such as steel-copper alloys, aluminum and plastics to name a few.

Rockwell testing falls into two categories: Regular Rockwell testing (e.g., C and B scales) and Rockwell superficial testing (e.g., 30 N and 30 T scales).

High Rockwell hardness numbers represent hard materials and low numbers soft materials.
