VP 12 US Versatile Port for Ultrasound Inspection



Systematic Approach to Data Collection

The VP-12-US offers a standard and systematic approach to data collection that is essential to establishing a repeatable and reproducible, condition-based monitoring program.

Consistent and Quality Acoustic Data

The VP-12-US standardizes location and method for accessing consistent and quality acoustic data regardless of ultrasound technician experience or enclosure rating.

Identifies Hazardous Faults

The VP-12-US easily identifies potentially hazardous faults such as arcing, tracking and corona in electrical distribution systems and switchgear.

Complies with IP2x Standard

The VP-12-US 1.2 cm (0.5) port opening complies with IP2x standard for safe maximum hole- size in switchgear to prevent accidental insertion of body parts.
