Digital Rockwell Hardness Testing Machine consists of forcing an indentor (Diamond or Ball) into the surface of a test piece 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.
RASNE series machines are suitable for Rockwell, Rockwell superficial & Rockwell cum Brinell tests. These are motorized digital Hardness testers having LCD display for easy hardness measurement. The results are displayed in 0.1 Rockwell unit for more accurate measurement.
Operation :
Various parameters of test can be set on front panel by operation of key board and observing LCD display Viz high/low limits, dwell time, auto/manual start, printer selection, scale selection etc. All set data can be verified edited by pressing SCL key one after another.
Machine operation is very simple. The normal mode is a bar followed by "SET" indication. Raise elevating screw slowly through bar indication 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 display with High/Good/Low indication. Lower down elevating screw. Panel will show normal mode for next test. Also when required 'AUTO START' on front panel by operation of key board & observing LCD Display then raise elevating screw slowly through bar indication till "SET" position then it will starts loading/unloading cycle automatically & hardness is shown on LCD Display with High/Good/Low indication.

Other Details:
Fine make hardness testers model TSM is manually operated_ These models are designed and developed after years of experience in this field. All the models are manufactured under strict quality at all manufacturing stages.
These models are suitable for testing hardness of metals and alloys of all kinds,. hard or soft, whether flat or round etc_ or of irregular shape. These Testers are simple rn design and easy to operate, still suite sensitive and accurate.
These models strictly conform to iS 3804. BS 891 Part-I &IL ASTM-E-18 for Rockwell test and IS 2281-2005_ BS 240. ASTM-E-10 for Brinell test and IS 5073-1988_ ATM-E-18 for Rockwell Superficial test.
TSM: This hardness tester is similar to TRB-250 machine in construction and with automatic weight selection. This is useful for carrying Rockwell and Rockwell Superficial Tests. The Rockwell Superficial method is useful for checking hardness of very thin sheets and surface hardness.

We are dedicatedly involved in providing an excellent quality array of Digital Rockwell Hardness Tester, for catering the various needs of our clients.

Hardness  Tester  TLRH-CURVE,  adopted  the  international  advanced  closed-loop  sensor  control technology, to achieve full automatic control and hardness testing process. The load system uses high- precision force value sensor and central controller to form a closed-loop loop to achieve full microsecond level tracking and control of the booster process. The measurement system uses high-precision displacement sensor with a hardness value resolution of 0.1 HR for accurate hardness results.
