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

One Thickness Gauge for Multiple Applications

Take advantage of powerful measurement features and a suite of application-specific software options for your current and future requirements.
  • Wide thickness range: 0,08 mm (0.003 in.) to 635 mm (25 in.) depending on material and transducer selection
  • Corrosion thickness gauging with dual element transducers
  • High Resolution software option of 0.001 mm or 0.0001 in. with single element transducers from 2.25 MHz to 30 MHz
  • THRU-COAT™ technology and echo-to-echo measurements to measure through painted and coated surfaces
  • Internal Oxide/Scale software option for boiler tube and internal oxide measurements
  • Multilayer software option to measure up to four layers simultaneously
  • High Penetration software option for attenuating materials such as fiberglass, rubber, and thick castings
  • Standard resolution: 0.01 mm or 0.001 in. for all transducers
  • Thickness, velocity, and time-of-flight measurements
  • Differential mode and reduction rate mode to track thickness variation and its percentage from a preset value
  • Time-based B-scan mode: 10,000 reviewable readings per scan
  • High Dynamic Gain technology with digital filters optimizes the starting gain setting based on calibration
  • V-Path Builder for custom V-path compensation in corrosion applications
