RSNE-250-T
Touch Screen Rockwell cum Brinell Hardness Tester
RSNE-250-T
Touch-screen Rockwell tester (leaflet name RASNE 250-T) with 187.5 and 250 kgf loads for Brinell testing with a 2.5 mm ball. Motorised cycle, 0.1 Rockwell resolution, USB data export and PC software; Brinell impressions are measured with the supplied microscope.
The RSNE-250-T, listed in the leaflet as RASNE 250-T, is the touch-screen Rockwell cum Brinell hardness tester built by Eklavya Techno Solutions in Ichalkaranji, India. It offers loads of 60, 100, 150, 187.5 and 250 kgf: the first three serve the regular Rockwell scales A to K, read on the capacitive touch screen to 0.1 Rockwell units after a motorised load, dwell and unload cycle, while the 187.5 and 250 kgf loads are used with the supplied 2.5 mm ball for Brinell scales HBW 2.5/187.5 and HBW 2.5/250. As on every ETS Rockwell cum Brinell machine, the Brinell impression is measured with the supplied microscope and converted with the tables rather than read from the screen.
The touch screen carries scale, dwell time and high/low limit settings, and every Rockwell result is logged with date and time for CSV export over USB or reporting in the PC software. The machine is intended for foundries, forges and component makers who test hardened parts by Rockwell and castings, forgings or annealed stock by Brinell on one bench. It has 230 mm test height and 133 mm throat depth, weighs about 70 kg, runs on single-phase 230 V and complies with IS 1586 (Part 2), ASTM E18, ISO 6508-2 and IS 1500 (Part 2).
Major load (total test force): 588.4, 980.7, 1471, 1839, 2452 N (60, 100, 150, 187.5, 250 kgf)
IS 1586 (Part 2) – Rockwell hardness test – verification and calibration of testing machines
ASTM E18 – Standard test methods for Rockwell hardness of metallic materials
ISO 6508-2 – Metallic materials – Rockwell hardness test – verification and calibration of testing machines and indenters
IS 1500 (Part 2) – Brinell hardness test – verification and calibration of testing machines

Grey and ductile iron castings, steel forgings, annealed or normalised steel and thick non-ferrous stock, where the coarse structure or softness makes a Rockwell diamond unsuitable. HBW 2.5/187.5 uses the same force-to-ball ratio as the classic 10/3000 test, so the numbers compare directly with Brinell values quoted on material certificates and drawings.
No. The touch screen displays the regular Rockwell scales to 0.1 units. For Brinell the 187.5 or 250 kgf load is selected by hand with the 2.5 mm ball, the motorised cycle makes the indentation, and the operator measures the impression diameter with the supplied Brinell microscope and reads HBW from the standard tables.
The RSNE-250 has the same load range and motorised cycle but a keypad and a built-in thermal printer. The RSNE-250-T uses a capacitive touch screen and exports over USB or to the PC software. The RASNB-TSFA adds automatic test-force selection from the screen and a thermal printer. All three measure the Brinell impression with a microscope.
The Rockwell function is verified to IS 1586 (Part 2), ASTM E18 and ISO 6508-2 and the Brinell function to IS 1500 (Part 2). Certified Rockwell C, Rockwell B and HBW 2.5/187.5 test blocks are supplied, and ETS offers calibration with traceable certificates, installation and AMC support across India.
Supplied: 50 mm flat and 38 mm V-groove tables, diamond RA indenter, 1/16 inch ball, 2.5 mm ball indenter, Brinell microscope, the three test blocks, telescopic screw sleeves, power cable, clamping device and cover. Optional: 5 mm step inserts, a jack rest for long heavy jobs and the PC software. Contact ETS if a printer is required on this model.
