Why choose 39DL Plus?

Reliable ultrasonic technology

The 39DL PLUS™ gauge builds on proven performance, offering reliable inspection using industry-standard ultrasonic technology for thickness inspection. It ensures accurate and reproducible measurements through outstanding signal quality, stable waveforms and optimized algorithms. It all comes from more than 35 years of experience in nondestructive testing (NDT), making it a reference for ultrasonic thickness inspection.

Built to withstand any environment

When working in harsh conditions, it is essential to have a robust and reliable tool. The 39DL PLUS™ is designed to ensure continuous operation even in the face of shocks, drops and heavy use. Its IP67-certified design fully protects it from dust and water, while compliance with MIL-STD-810H ensures resistance to explosive atmospheres, shock and vibration. The device can operate smoothly over a wide temperature range, from -10 °C to 50 °C (14 °F to 122 °F). The rubber protection also provides greater impact resistance and a more secure grip, making it even more reliable in the field.

Designed for the operator: practical and intuitive

Designed to offer convenience and ease of use, the 39DL PLUS™ is lightweight and easy to carry, weighing only 0.83 kg. The ergonomic keypad provides quick access to all functions and can be used comfortably with either the right or left hand. The built-in datalogger allows for quick storage of thickness measurements and waveforms, optimizing workflow. The device supports predefined and customized configurations for single- and dual-element transducers, reducing setup time and increasing inspection efficiency. In addition, the access control system protects instrument functionality with passwords, ensuring data security.

Advanced readability and connectivity

The transflective VGA color display ensures excellent visibility in any environment, both indoor and outdoor, thanks to customizable color configurations. For an even more detailed view of results, the meter is equipped with a VGA output, which allows connection to a computer or external monitor, offering greater convenience in viewing data and analyzing measurements.
