Supports the following standards: ASTM C597, ASTM C597, EN12504-4, BS 1881 PART 203, ISO1920-7:2004, ISO1311 The Pundit Lab ultrasonic tester can be used to detect the presence of cracks, voids and other imperfections in concrete, as well as determine and monitor the strength and deterioration of concrete, which may have occurred due to age, fire, frost or chemical attack. The Pundit Lab devices provide optimized pulse shaping, automated transmission settings and a range of powerful transducers. They allow analysis of the received signal and manual triggering directly on the instrument. Full remote control of all transmission parameters, data logging function and functionality that can turn your PC into an oscilloscope. USB interface and data analysis software provide data analysis and export to third party programs through Open interface such as LabVIEW. Pundit Lab consists of: display unit, 2 transducers (54kHz), 2 BNC cables 1.5 m, couplant, calibration rod, battery charger with USB-cable, 4x AA (LR6) batteries, data carrier with software, documentation and carrying case. The Pundit Lab+ comes with an extended feature set, making it particularly suitable for on-site measurements. Functions include, an integrated gain stage making an external amplifier unnecessary when using long cables or exponential transducers, a real time stamp for recording the time of measurement, a data review list that allows previous measurements to be viewed on site, and a correlation to compressive strength either directly from pulse velocity or in combination with a rebound value (SONREB method).
