Universal Testing Machine
UNIVERSAL TESTING MACHINE- Mechanical Loading 40 Tones
Universal testing machine is designed to perform tensile, compression, bending and shear tests on must widely varying materials, both in the form of test pieces and as finished products. Hardness test on metals can also be performed.
LOAD/ELONGATION RECORDING SYSTEM
A continuous roll (a strip chart) type load – elongation recorder is provided for plotting load – elongation graph. Horizontal movement of the rack products load ordinate of the diagram and drum rotation to elongation ordinate, in the ratio of either 1:5 or 1:10.
ACCURACY AND CALLIBRATION
RE Universal testing machines are precisely controlled for accuracy and reliable calibration during every stage of manufacture. The machines are calibrated in accordance with B.S. 1610 and I.S. 1828-1975. RE Universal testing machine comply with grade ‘A’ of B.S. 1610:1964 and grade 1.0 of I.S. 1828-1975.
An accuracy of /- 1% is guaranteed form 20% of the load range selected to full load. Below 20% of the selected range the maximum permissible error is 0.2% of the full load reading.
• Loading accuracy as high as 1%
• Straining rate to cover a wide range of materials.
• Continuous roll tape load elongation recorder.
• High reading accuracy due to large size and design or dial.
• Simple controls to facilitate ease of operation.
• Fully enclosed and protected load measuring system.
• Wide range of standard and special accessories including load stabilizer.
• Robust straining frame.
• Suitable for standard specimen and also structures.
•Motorized UP/DOWN movement of lower crosshead to enable easy and rapid fixing of test specimen.
