39DL PLUS™ Ultrasonic Thickness Gauge

Simplify ultrasonic thickness testing procedures with a portable, dependable, fast, and connected gauge—the 39DL PLUS instrument. Also known as the 39DLP™ gauge, this advanced handheld instrument can be used as a precision or corrosion thickness gauge for demanding applications.

Building on the success of its predecessor, the 39DLP gauge offers faster data transfer, quicker scanning up to a 60 Hz update rate, and integrated wireless connectivity to make inspection workflows more efficient.

Connected: Data transfer options include integrated Wi-Fi^®, integrated Bluetooth^®, USB port, RS-232 port, and a removable microSD card*

Fast: Scan for minimal thickness areas at an update rate that is two times faster than that of its predecessor and comparable handheld thickness gauges (up to 60 Hz vs. 30 Hz)

Versatile: Use the broad range of dual and single element transducers from Evident to handle diverse applications with one gauge

*Wi-Fi^_® and Bluetooth^® are pending certification in some regions. Contact your local Evident representative for details on their availability.

Affordable Part Scanning

The 39DLP instrument offers a breakthrough 60 Hz update rate for handheld thickness gauges, making it an asset in scanning applications.

Works as an affordable alternative for inspection codes that require a 60 Hz 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 corrosion-related assets.
