Digital Rockwell Hardness Tester By Vmc Instruments

Digital Rockwell Hardness Tester has motorised automatic operation cycle i.e. load/dwell/unload. The Preliminary Test Force is 98.07N (10kgf). Total Test Force is 588.4, 980.7, 1471N (60,100,150 kgf). Test Force Selection is by external mechanical dial. The machine covers Rockwell scale A, B, C, D, F, G. The system has bar indication on display for Preload. User can set Preload Dwell time, Dwell time for Total Load and Elastic recovery Dwell. The operation is easy with keyboard entry through reliable membrane switches for scale/HI-GO-LO/Dwell time selection. The scale display is with 0.1 Rockwell Resolution.

The system has real time measurement and indication with Digital Dial Indicator of 1 micron resolution.

There is inbuilt thermal printer for report printing. It gives results indicating serial
number of tests, hardness scale, hardness value and high / good / low indication.

The above Rockwell measurement system can be attached to basic Rockwell hardness tester. And it is easy to adopt it by either manufacturer or customer. Here basic mechanical machine with required repeatability is necessary.

The measurement system consists of Digital dial, Interface circuit, display, keypad. A power supply with Printer is provided in a separate module.

Options available are:
1. Digital Rockwell Hardness Tester with details as above.
2. Digital Rockwell Cum Rockwell Superficial Hardness Tester ( T & N scales additional)
3. Conversion kit for 1 & 2.
