The Masterscan D-70 offers the inspector a fully capable and functional set of tools and software for inspection across all applicated. Constructed using impact resistant materials and designed to meet IP67 standards, the D-70 offers excellent water resistance. The D-70 has a color transflective VGA display, providing high visibility in any lighting condition, with the enhanced user interface and a full screen A-Scan display is available at the touch of a button. Features can be added and new upgrades performed in the working environment, reducing downtime and increasing work flexibility. High levels of near surface resolution, penetrating power (450V pulser – square and spike) and excellent signal to noise ration are key functions of the Masterscan D-70. Capabilities include Encoded B-Scan, Advanced Thickness logging and Dryscan capability in a portable enclosure.
