Analogue Universal Testing Machines – TUN Series

• Robust Construction: Precision-engineered machines designed for reliable testing of metallic materials.
• Capacity Range: Available from 100 kN to 2000 kN.
• Testing Functions: Suitable for tension, compression, and transverse testing.
• Autographic Recording: Continuous-roll Load vs. Elongation recording for test documentation.
• Available Models:
  • TUN-100
  • TUN-200
  • TUN-400
  • TUN-600
  • TUN-1000
  • TUN-2000
• Loading Accuracy: Within ±1%.
• Standards: Designed in conformity with IS 1828 / BS 1610.
• Applications: Suitable for industrial, laboratory, research, and educational environments.
• Optional Attachments: Available for specialized testing, including:
  • Brinell testing
  • Shear testing
  • Bend testing
  • Rope testing
  • Belt testing
  • Bolt & nut testing
  • Pull-out testing

• 1. A model for every lab size From compact 100 kN units to the heavy-duty 2000 kN machine, the TUN range lets teaching labs, testing houses and production floors pick the capacity that matches their work, without changing brands or operating style.
• 2. Four dial ranges, one machine Every model lets the operator switch between four load scales. On the TUN-100, readability improves from 0.2 kN to 0.02 kN per division, so light specimens are read finely and heavy ones can still be pulled to full capacity.
• 3. Load readings you can rely on Force is measured within ±1%, and the build follows IS 1828 and BS 1610, the references most Indian and international labs expect.
• 4. A paper record of every test The built-in roll recorder plots the load against elongation as the test runs. You get a physical trace of how the specimen behaved, ready to attach to a test report.
• 5. Three tests, one frame Pull, crush or bend a specimen on the same machine. Optional fixtures extend it further to Brinell hardness, shear, bend, rope, belt, bolt and nut, and pull-out testing.
• 6. Supplied with the essentials Each machine ships with grips for round and flat specimens, compression platens, roller supports and punch tops, so you can begin testing as soon as it is commissioned.
• 7. Room for larger specimens Daylight openings reach up to 900 mm and the piston travels up to 300 mm on the bigger models, which accommodates long bars and bulky samples.
• 8. Easy power requirements The machines run on a standard 3-phase, 415 V, 50 Hz supply. Motor ratings start at just 1.5 HP on the 100 kN and 200 kN models.
• 9. Backed by experience FSA has built testing machines since 1977, and Testwin provides sales and service support across India.
