Packaging Type Wooden Box Digital Rockwell Hardness Tester, Parameter HRC, Frequency 50 Hz

Rockwell and digital rockwell hardness tester consists of forcing an indentor diamond or ball into the top layer of a sample item in two steps i. E. First with preliminary test force and thereafter with additional test force and then measuring depth of indentation after removal of additional test force remaining preliminary test force active for measurement of hardness value. Rasn, Et series machines are compatible with Rockwell products and rockwell superficial tests. These are motorized digital hardness testers having lcd display for easy hardness measuring. The results are display in 0. 1 rockwell unit for more accurate measurement. Operation various parameters of test can e set on front panel by operation of key board and observing lcd display viz high / dwell time, Low limits, Auto / manual start, Scale selection, Printer selection etc. All set data can be verified / edited by pressing scl key one after anothermachine operation is very simple. The normal mode is a bar followed by set indication. Raise elevating screw slowly through bar indicator till set position which will show press start indication. Now press start button. Loading / unloading cycle will be completed and hardness is shown on LCD screen equipped with high/ good / low indication. Lower down elevating screw. Panel will show normal mode for next testtechnical specifications modelunitrasn et major loadn kgf 147. 1, 294. 2, 441. 3, 588. 4 980. 7, 1471 15, 30, 45, 60, 100, 150 minor loadn kgf 29, 42, 98. 07 3, 10 max test heightmm230depth of throatmm133net wt.
