Chicago, IL, USA January 3rd , 2010 James Instruments Inc. manufacturer of the world's most advanced Non Destructive Test Equipment for construction materials officially announces the release of the V-Meter™ Mk III PC control feature. The PC control feature makes the already successful V-Meter Mk III ™ the most advanced and industry leading Ultrasonic Pulse Velocity meter.

Central to the improvement of the concrete infrastructure are tools that evaluate the condition of existing construction. Destructive and non-destructive testing (NDT) techniques are applied. Destructive tests can provide direct information, but are relatively expensive, time-consuming and cause damage to the structure. Destructive test results often cannot be evaluated using statistical approaches because the number of locations in the structure that can be tested without damage to the structure is limited. On the other hand, NDT techniques are relatively inexpensive to apply, and they can detect, localize, and characterize flaws and damage in concrete structures without leaving any undesirable discontinuities or causing damage to concrete members.

The V-Meter™ Mk III is widely used and accepted for quality control and inspection of concrete. It can measure and correlate concrete strength to standard strength measurement, permitting non-destructive testing of complete structures. It will identify honeycombs, voids, frozen concrete, cracks and other nonhomogenous conditions in concrete. Ultrasonic testing can be applied to new and old structures, slabs, columns, walls, fire damaged areas, hydroelectric structures, pipe, prefab and pre-stressed beams, cylinders and other
concrete forms. The V-Meter Mk III™ can also be used on wood to detect knots, shakes, delamination splits, grain orientation, windfall cracks and presence of decay and rot. Ceramics and other fine grain materials can be tested with the V-Meter Mk III ™using higher frequency transducers. A wide range of transducers are available.

Typically, the 54 KHZ transducers are used for concrete testing – the signal wavelength is about 3 inches (75mm). Finer materials require higher frequencies for optimum resolution. The basic V-Meter Mark III™ contains a transmitter, a receiver and a very accurate high speed electronic clock. The transmitter generates an electrical pulse which when applied to a transmitting transducer, converts the electrical energy into a pulse of ultrasonic mechanical vibration. This vibration is coupled with the specimen under test by placing the transducer in contact with the specimen. At another selected point on the specimen another receiving transducer is coupled by mechanical contact. Each transmitted pulse of energy registers on the high speed clock. The first energy wave reaching the receiving transducer is converted back to an electrical signal and turns off the clock. The elapsed time is displayed on the LCD in 0.1 microsecond increments.

Ultrasonic Pulse Velocity measurements such as P-Velocity, Poisson’s ratio and Young’s modulus are critical for the overall quality assurance of a structure. The new PC control function will enable the end user to easily obtain these values by controlling all functions via his PC. “The PC Control function software now makes the V-Meter Mk III™ easier to work with while on the field but also excellent when conducting experiments in a laboratory environment.”, says Nestor Chonillo, Vice President of James Instruments Inc. The PC control function software allows you to trigger a pulse wave remotely all while recording and registering each test result automatically to the PC.
