Release of V-Meter MK IV™

James Instruments Inc. Releases the V-Meter MK IV™Ultrasonic Pulse Velocity System For Finding Voids and Cracks, and Determining Other Material Properties

October 19th, 2011, Chicago, Illinois - James Instruments Inc. announces the release of the V-Meter MK IV™, ultrasonic pulse velocity system for finding voids, crack and determining other material properties in concrete, wood, ceramic, masonry and other coarse grain materials. Cracks, voids and honey combs are most sensitive to the stress waves caused by ultrasonic testing, this makes the V-Meter MK IV™ one of the most effective methods for determining quality of coarse grained materials. The new system utilizes the latest in software and electronics technology to simplify testing and help interpret the data generated.

The V-Meter MK IV™ system features:

• A direct digital read-out of transit time, and read out of wave form on daylight display, back lit LCD.

• Rugged and splash resistant case built for tough construction environments. Portable, and light weight with both rechargeable battery and standard A-C power.

• Includes a signal and trigger output for use with external oscilliscope or other data input device. Digital calibration means no special bar required. Trigger levels and Signal amplification can be digitally adjusted.

• Conforms to ASTM C-597, BS 1881-203 and other international standards

• USB interface for computer control. Veelinx™ software allows complete control of the system as well as data upload to a PC and data analysis.

• Direct reading of calculated P-wave velocity and S-wave velocity. The unit can also calculate modulus of elasticity of material using optional S-WaveTransducers. Direct reading of Poisson's ratio

• A large range of Accessories and Ultrasonic Transducers available. Standard Transducers available from 24KHz to 500 KHz enable the unit to test ceramics, graphite, mass concrete pores, and wood. Exponential Transducers for rough surfaces, as well as underwater transducers are also available. Finally a Pre-Amplifier is available for help with long distances or highly attenuative materials.

The Complete System includes the Veelinx™ Software which features:

• Controls All Operational Parameters of V-Meter MK IV from a Personal Computer

• Automatic Upload of Data for Long Term Laboratory of Production Analysis

• Data Storage in Standard ASCII format for use in popular Spreadsheet Software and other Office Personal Computer Applications.

“The V-Meter MK IV™ is our fourth generation of this system and represents not only our continued commitment to the test method, but also our commitment to bringing the latest technology to the testing community” says Michael W. Hoag, President of James Instruments Inc.

James Instruments Inc. is the leading manufacturer of non-destructive test equipment for construction materials, specifically concrete, ceramic, wood, masonry, mortar, gypsum and other coarse grained materials. We supply the instruments that: measure strength, both compressive and tensile, locate rebar and other objects in concrete and masonry, determine density and analyze materials ultrasonically, analyze corrosion and, finally, determine moisture in concrete and other construction materials. And more. James Instruments -- rugged, quality equipment for field use -- backed by factory service and an ongoing program of research and development.
