The 39DL PLUS™ is a versatile handheld ultrasonic thickness gauge engineered for precision and corrosion thickness measurements on metals, plastics, composites, glass, rubber, and ceramics. Ideal for pipes, tanks, pressure vessels, hulls, and other structures affected by corrosion or erosion, it combines high accuracy, rapid scanning, and advanced software options in a rugged, field-ready design. Featuring a color transflective VGA display, intuitive keypad, and built-in data logger, the 39DL PLUS™ enables fast, reliable measurements with seamless connectivity through Wi-Fi®, Bluetooth®, USB, and RS-232.

The gauge supports dual and single element transducers, including optional software for THRU-COAT™ technology, High Resolution, Multilayer, High Penetration, Internal Oxide/Scale, and Encoded B-scan applications. Its Automatic Probe Recognition and V-Path Builder simplify calibration and ensure precise measurements even on coated, painted, or complex surfaces. With IP67-rated rugged housing, military-tested durability, and high-temperature capability up to 500 °C (932 °F), the 39DL PLUS™ is built to perform in the toughest inspection environments.
