Pundit Lab

The most versatile ultrasonic pulse velocity test equipment for concrete

Reference Standards: EN12504-4 (Europe); ASTM C 597-02 (North America); BS 1861 Part 203 (UK); ISO1920-7:2004 (International); IS1311 (India)

Pundit Lab

Featuring on-line data acquisition, waveform analysis and full remote control of all transmission parameters

The Pundit Lab has all the functions of the classic Pundit 7, but offers additional benefits. Designed with laboratory use in mind, its compact size, rugged construction and optimized power consumption make it equally suitable for on-site use.

Along with the traditional transit time and pulse velocity measurement, Pundit Lab offers path length measurement, perpendicular crack depth measurement and surface velocity measurement. Optimized pulse shaping gives greater transmission range at lower voltage levels. This coupled with automated combination of the transmitter voltage and the receiver gain ensures an optimum received signal level ensuring accurate and stable measurements. The waveform can be viewed either via an external oscilloscope connection or directly on a connected PC screen.

Full remote control capability completes the package.

Benefits

Remote Control: A USB connection and the Pundit Link application allow full remote control of all Pundit
Lab features, on-line data acquisition, waveform analysis, manual triggering and data upload.

Versatility: Basic measurements of pulse velocity or path length. Compound measurements of crack
depth and surface velocity. Non volatile storage and download to PC is ideal for uniformity testing.

Multiple Power Supply Options: Pundit Lab runs on battery supply, mains supply via AC adaptor and
can also be powered from a PC via the USB connection.

Wide range of transducers: Pundit Lab supports a wide range of transducers from 24 kHz up to 500 kHz, making it suitable not only for concrete and rock, but also for other materials such as graphite,
ceramics, wood, etc.

Measurement Example

Input: Pulse velocity

 Measured transmission time
Computed result (path length, e.g. wall thickness)
Measurement Example
Ultrasonic instruments are mainly used to measure the pulse velocity. In addition to this, the Pundit Lab can also determine the path length (e.g. wall thickness) as in the above example where the pulse velocity is known.

Compound Measurements

Compound measurements are made simple by automatic calculation of surface velocity and perpendicular
crack depth.
