Nova Engineers And Instruments

Other Details:

• This Rockwell Hardness Tester combines high precision and easy operation. Manual zero setting and a large dial indicator for accurate hardness value reading. The Nova range of Rockwell hardness tester range start from low cost Analog models to sophisticated and advanced load-cell types models. It is highly accurate, reliable, durable, and also cost effective

Features:-

•  Rockwell Hardness Tester ( Model : RAS):– Automatic Load selection with automatic zero setting dial gauge.
• Rockwell Hardness Tester ( Model : RASM):– Driving motor with automatic loading and unloading technique with automatic zero setting dial gauge
• Rowell Cum Brinell Hardness Tester ( Model : RAB):– Similar to RAS with additional Brinell Test Loads of 187.5 kgf & 250 kgf.
• Rockwell Cum Brinell Hardness Tester ( Model : RAB – 250):- Similar to RAB but are of bigger capacity.
• Rockwell Cum superficial hardness Tester (Model : TWIN ):– Driving motor with automatic loading and unloading technique with automatic zero setting dial gauge. They are operated manually. They are guided with a Diamond holder is in a ball cage, which enables testing of small pins having diameter Less than 6 mm (up to 3mm diameter).

A Metal Hardness Tester is a device used to measure the hardness of metallic materials, which reflects a material’s resistance to deformation, indentation, or scratching. Hardness is a key indicator of a metal’s strength, wear resistance, and durability. These testers are widely used in quality control, manufacturing, metalworking, heat treatment, and material research.

Other Details:

• Load cell based close-looped control.
• Brinell, Rockwell, Vickers three testing methods.Selection of plastic Rockwell scales (specific demands are supplied depending on the contract).
• Hints for indentors when the scales are selected.
• Automatically apply major load and minor load.
• On screen conversion of hardness scales.
• Result can be exported in “Excel” using flash drive

Other Details:
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.
