Universal testing machine(UTM): A u niversal testing machine (UTM) , also known as a universal tester, materials testing machine or materials test frame, is used to test the tensile strength and compressive strength of materials. An earlier name for a tensile testing machine is a tensometer. The "universal" part of the name reflects that it can perform many standard tensile and compression tests on materials, components, and structures (in other words, that it is versatile). Universal Testing Machine is designed for testing materials and other materials under tension, compression bending, transverse and shear loads. Components of Universal Testing Machine: Several variations are in use.Common components include: 1.Load frame - Usually consisting of two strong supports for the machine. Some small machines have a single support. 2.Load cell - A force transducer or other means of measuring the load is required. Periodic calibration is usually required by governi...

Ultrasonic pulse velocity test: An ultrasonic pulse velocity test is an in-situ, nondestructive test to check the quality of concrete and natural rocks. In this test, the strength and quality of concrete or rock is assessed by measuring the velocity of an ultrasonic pulse passing through a concrete structure or natural rock formation. This test is conducted by passing a pulse of ultrasonic wave through concrete to be tested and measuring the time taken by pulse to get through the structure. Higher velocities indicate good quality and continuity of the material, while slower velocities may indicate concrete with many cracks or voids. Technical Specifications: Temporal measure resolution: 83 nS - filter passing band:20-80KHz - amplificator gain :50dB - minimum level of the trigger signal: 208 Mv 2 TX / RX channels, - contact probes, freq. 55 KHz - data saving on internal memory, - 3" display to visualize the time of fly (T.O.F.) and the speed of waves transmissi...
