Precision You Can Measure. Performance You Can Trust.
Our Analogue Universal Testing Machines are robust, precision-engineered systems designed for reliable testing of metallic materials. Available from 100 kN to 2000 kN, the TUN Series supports tension, compression, and transverse testing, with continuous-roll Load vs.Elongation autographic recording. Models include TUN-100, TUN-200, TUN-400, TUN-600, TUN-1000 and TUN-2000. With loading accuracy within ±1% and conformity to IS 1828 / BS 1610, these machines are suitable for industrial, laboratory, research and educational applications. A range of optional attachments is available for specialized tests, including Brinell, shear, bend, rope, belt, bolt-nut and pull-out testing.
