Ultrasonic Thickness Gauge 39DL Plus

The 39DL PLUS™ gauge works as a precision or corrosion thickness gauge for demanding applications. Integrated Wi-Fi®, Bluetooth®, USB, RS-232, and a removable microSD card. Scan for minimal thickness areas at a 2 times faster display update rate. Tackle multiple thickness applications with full line of dual and single element transducers.

SPECIFICATION

Parameter	Spesifikasi
Dual element transducer measurement mode	Time interval from a precision delay after the excitation pulse to the first echo
THRU-COAT™ measurement	Measurement of true metal and coating thicknesses with a single back-wall echo (with D7906-SM and D7908 transducers)
Thru-Paint Echo-to-Echo	Time interval between two successive back-wall echoes to eliminate paint or coating thickness
Single element transducer measurement modes	Mode 1: Time interval between the excitation pulse and the first back-wall echo Mode 2: Time interval between the delay line echo and the first back-wall echo (with delay or immersion transducers) Mode 3: Time interval between successive back-wall echoes following the first interface echo after the excitation pulse (with delay line or immersion transducers) Oxide: optional Multilayer mode: optional
