The PMX4-DL High Penetration Thickness Gauge is a powerful ultrasonic measurement solution specifically engineered for materials that are difficult to penetrate due to inconsistent grain structures, varying densities, or excessive thickness. Designed with advanced high-voltage pulser technology and optimized low-frequency filtering, the PMX4-DL delivers reliable and accurate thickness measurements across challenging materials and demanding industrial environments.
Built for versatility and precision, the PMX4-DL supports multiple ultrasonic measurement modes including Pulse-Echo, Echo-Echo, and Echo-Echo Verify, enabling accurate inspections on coated and uncoated materials. Its adjustable 200V spike pulser, 400V square wave pulser, and tone burst technology provide exceptional penetration performance for low-frequency transducers ranging from 500kHz to 10MHz.
The device is ideal for inspecting materials such as fiberglass, carbon fiber, cast metals, HDPE, FRP, rubber, lead, steel, and aluminum, making it highly effective for applications including storage tanks, aerospace composites, pipes, boat hulls, conveyor belts, and composite plastics.
Equipped with a high-resolution VGA grayscale display, advanced A-Scan and B-Scan visualization modes, onboard data logging, USB-C connectivity, and customizable user setups, the PMX4-DL enables technicians to perform faster inspections, improve measurement reliability, and streamline reporting workflows. Its rugged aluminum body, long battery life, and portable design make it suitable for both field and industrial inspection environments.
By combining deep penetration capability, intelligent signal processing, and advanced ultrasonic analysis features, the PMX4-DL helps professionals confidently inspect complex materials while reducing downtime and improving operational efficiency.
