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.
Thickness measurement is a major application of the Masterscan series and good data logging tools are essential to productivity. The popular block/location/Reading-Number format is available as standard. With the corrosion software option, users can create and populate two dimensional grids of readings, with A-Logs, B-Scans, historical readings and notes optionally attached to each thickness log.
With the Time-Controlled Gain (TCG) option, the gain of the receiver can be varied along the beam path to compensate for beam-spread and attenuation. This brings equivalent reflectors at different depths to equal heights on the A-Scan and allows a simple gate to act as the reporting level for the inspection. TCG can be generated from reference echoes in the same way as DAC, or can be converted from a pre-existing DAC curve.
With this option enabled, measurements of indication level (L), Attenuation Factor (AF), and indication rating (IR) are calculated and displayed in accordance with AWS D1.1
The Dryscan option adds a tuned pre-amplifier to the received signal, allowing comparative transmission testing of composite materials which cannot be inspected using traditional techniques. Used in conjunction with soft-tip and roller probes, no couplant is required, so honeycomb structures or carbon fibre panels are easily assessed for delaminations and disbonds.
UT-Lity software provides everything you need to manage your inspection data. The standard version is FREE with every instrument and gives you the ability to view, move and manage Calibrations, A-Scans, B-Scans and Thickness Logs both on the instrument and on your PC. With UT-Lity you can also create customized inspection report templates, cut-n-paste information to other applications and create printable pdf documents.
