Ultrasonic Pulse Velocity - Pundit Lab
The Pundit Lab is an ultrasonic pulse velocity (UPV) test instrument which is used to examine the quality of concrete.
It features online data acquisition, waveform analysis and full remote control of all transmission parameters. Along with the traditional transit time and pulse velocity measurement, the ultrasonic test equipment 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, guaranteeing accurate and stable measurements. An integrated waveform display allows manual triggering of the received waveform.
Features
• Integrated waveform display
• Remote control: A USB connection and the Pundit Link application allow full remote control of all features of the ultrasonic test equipment Pundit Lab.
• Open interface: full remote control of the instrument is also possible with third party software
• Direct data logging on the PC
• Multiple Power Supply Options: the ultrasonic test equipment 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: The ultrasonic test equipment 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, woods, etc. Exponential transducers for rough surfaces and shear wave transducers for estimation of dynamic modulus of elasticity complete the portfolio.

Concrete Rebound Test Hammer - Original Schmidt
The quality of concrete is mainly judged by its compressive strength directly affecting the load-bearing capacity and durability of concrete structures. Proceq invented the Original Schmidt, the world’s first and now most widely used test hammer for analyzing the compressive strength of concrete properties.
The Original Schmidt will hit the concrete at a defined energy whereas its rebound is dependent on the hardness of the concrete and is measured by the instrument. The Original Schmidt is available in models with different impact energies. Each test hammer is designed for a specific test application, in order to meet the needs of the customers to investigate a wide range of material types and sizes, such as bridge decks, thin walls, cast stone components or small components.
Concrete Test Hammer - SilverSchmidt
The SilverSchmidt ST/PC is the first integrated concrete test hammer featuring true rebound value and unmatched repeatability.
Two factors contribute to the improved performance of this concrete test hammer over its predecessors:
- Velocity based detection of the rebound quotient
- The lightweight hybrid design of the impact plunger is made from aerospace alloy, matched to the elastic properties of the concrete and equipped with a hardness steel cap
Independent validation testing by BAM (Federal Institute for Materials Research and Testing, Germany) has shown the SilverSchmidt ST/PC to have less dispersion than the classical concrete test hammer over the entire range.
The unique design and high quality construction of the concrete test hammer SilverSchmidt ST/PC makes rebound hammer testing quicker and more accurate than ever before.
Rebar Detection for concrete Testing
Concrete constructions rely on reinforcing steel to provide the necessary tensile strength. Drilling through those reinforcing bars is a costly business that can be dangerous: Hitting a rebar while boring into the reinforced concrete can destroy the drilling instrument and can severely weaken the concrete structure. An instrument for non destructive rebar detection that quickly and accurately determines the location of the reinforcing bars in the concrete will significantly decrease construction time and costs.
Sufficient concrete cover above the reinforcing steel is one of the key factors in determining the design life of a concrete structure. Correct assessment of the concrete cover using a cover meter is an essential test during construction.
The rebar detection instrument Profoscope has a unique real-time visualization mechanism, similar to a scanner, allowing the contractor to actually see the location of rebars beneath the concrete surface in real time. The Profoscope+ features data storage for automatic collection of data to make rebar detection more efficient.
The Profometer PM-6 combines rebar detection, diameter estimation and the statistical analisys of concrete cover in one instrument. Both of these non destructive testing products use eddy current technology.
Rebar Detector and Covermeter - Profoscope
The Profoscope is a versatile, fully-integrated rebar detector and cover meter with a unique real-time rebar visualization allowing the user to actually “SEE” the location of the rebar beneath the concrete surface to a maximum depth of 180 mm. This is coupled with rebar-proximity indicators and optical and acoustical locating aids. Rebar diameter can also be estimated within the specified testing range. The Profoscope combines these unique features in a compact, light device that allows the user to operate this rebar detector with one hand making the task of locating rebars a simple and efficient process. In addition, Proceq’s rebar detector convinces through its intuitive user interface making rebar detection easy.
Features
- A rebar detector with real-time visualization of the rebars beneath the instrument
- Visual indication of rebars in close proximity
- The Profoscope is a rebar detector with the ability to identify the mid-point between rebars as well as the orientation of rebars
- Optical and acoustical indication of rebar location and minimum cover alert
- This rebar detector offers neighboring bar correction
- Regional settings (metric, imperial)
- Cordless and single handed operation
- Switchable display backlight for dark environments
- A rebar detector with icon-based language independent menus
- Start-up test kit allows user to familiarize him/herself with all functions in a comfortable environment, wasting no time on site
Applications
- Rebar detector
- Measurement of concrete cover
- Measurement of rebar diameter
- Checking for minimum cover
- Map out the rebar grid and cover for corrosion studies (with Canin+)
- Rebar grid examination for planned load changes on the structure
- Testing on pipe piles
