PUNDIT 7 Ultrasonic Testing Instrument

The PUNDIT 7 ultrasonic pulse velocity tester is a concrete testing instrument with many new features, including an innovative signal strength indicator bar icon on the display screen. Although the instrument is extremely easy to operate, it can be considered powerful even for expert level users. It can be directly controlled by a PC or factory control system, so users can fully realize remote control functions: it is an ideal choice for extended testing or large-scale production testing applications in research laboratories.
