Elcometer 205, 206 & 206DL Ultrasonic Thickness Gauges - Discontinued


Replaced by the Elcometer MTG6

The Elcometer 205, 206 & 206DL are hand-held ultrasonic thickness gauges that allow you to make reliable thickness measurements or scan a length of material for defects, or for the thinnest point.

Each gauge comes with 3 calibration options: single point, 2 point and speed of sound selection - allowing accurate measurements on a wide range of materials. Compatible with a wide range of measurement transducers, these ultrasonic thickness gauges are available with or without memory and all come with a  backlight for measuring in darkened environments. Transducers are supplied separately.
