The PVX v2.0 is our most advanced precision A-Scan scope, commonly used in the aerospace, automotive, stamping and precision machining industries. The versatility and transducer options offer a measuring range from very thin to extremely thick, with exceptional resolution. There’s a variety of features and tools to accommodate a number of material types and applications. The electronic platform is FPGA driven for speed and accuracy. The screen refresh rate at 25 Hz (b&w) and 60 Hz (color), contributes to the overall responsiveness of the gauges. The built-in data logger has two file format options, grid or sequential, and is equipped with an internal 4 GB SD card for memory. Connectivity to a standard PC or Mac via USB-C, and used in conjunction with our Windows® PC or MAC OSX reporting software available for download, at no charge, on our website.
