39DL PLUS™ Ultrasonic Thickness Gauge

Faster Thickness Results

Streamline your ultrasonic thickness inspection process with one fast, connected, and reliable handheld gauge. The 39DL PLUS™ gauge works as a precision or corrosion thickness gauge for demanding applications.

With world-class ultrasonic capability, fast scanning speeds up to a 60 Hz update rate, and fully integrated wireless connectivity, our flagship handheld thickness gauge delivers results you can trust in a seamless workflow.

  • Connected: Integrated Wi-Fi®, Bluetooth®, USB, RS-232, and a removable microSD card
  • Fast: Scan for minimal thickness areas at a 2 times faster display update rate (Up to 60 Hz versus 30 Hz on the predecessor model and comparable handheld thickness gauges)
  • Versatile: Tackle multiple thickness applications with our full line of dual and single element transducers

Affordable Part Scanning

With breakthrough scanning speeds, the 39DL PLUS instrument offers an industry-leading 60 Hz update rate for handheld thickness gauges.

  • Works as an affordable alternative for inspection codes that require a 60 Hz display update rate for scanning; get the scanning speed of a flaw detector with the ease of use of a thickness gauge
  • Find thin spots more easily when scanning for minimal thickness areas on pipes and other assets affected by corrosion
