V2 Ultrasonic Calibration Block Stand
Calibration Block Stand
1.For IIW2/V2 and MAB Blocks
2.High-quality Acrylic, Lightweight and portable
3.Hands-Free, Efficiency, Stability
V2 ultrasonic calibration block stand is an essential accessory for nondestructive testing (NDT) technicians. Its primary function is to provide a stable, hands-free, and repeatable platform for calibrating and verifying ultrasonic flaw detectors and transducers using a standard V2 (or IIW/MAB) calibration block.
V2 block stand is a simple yet vital tool that enhances the accuracy, repeatability, and efficiency of the ultrasonic calibration process, which is the foundation for reliable inspection results.

Application of IIW2/V2/MAB Ultrasonic Test Block Stand
IIW2/V2/MAB ultrasonic test block stand is a specialized fixture designed to securely and precisely hold a V2 calibration block during the setup and calibration of ultrasonic flaw detector.
Its primary applications and benefits include:
Secure and Consistent Positioning:
It firmly clamps the V2 block in a fixed, stable position, eliminating human hand-held variability. This ensures that the coupling (typically using couplant) between the ultrasonic probe and the block's surface is consistent and repeatable for every calibration.
Enhanced Calibration Accuracy:
By providing a perfectly flat and stable surface, the stand allows the technician to perform highly accurate calibration steps. This includes setting the material velocity and establishing the time base (or distance range) of the UT instrument's display. The precise distance from the notches (e.g., 25mm, 50mm, 100mm) to the probe is critical for this.
Probe Alignment and Angle Verification:
The stand ensures the probe is correctly aligned perpendicular to the scanning surface. This is essential for accurately determining the refracted angle (e.g., 45°, 60°, 70°) of angle beam probes by using the block's radius arc.
Resolution and Sensitivity Checks:
It facilitates the assessment of horizontal linearity (resolution) and vertical linearity using the depth steps and the 100mm radius. It also helps in setting the sensitivity/gain of the equipment by providing consistent echoes from reference reflectors like the 1.5mm or 3mm side-drilled holes.
Improved Efficiency and Safety:
It frees the technician's hands to operate the UT instrument, significantly improving workflow efficiency. It also protects the expensive and precision-machined surface of the V2 block from being dropped or scratched.
