Explorer II Ultrasonic Workstation
 The
Explorer II Ultrasonic Workstation is a rugged stand alone flaw
detector with a large (10.4") TFT built-in display. The ability
to configure as a high- or low-frequency spike pulser instrument
with high power toneburst (as an option) and act as a high-speed
controller and data acquisition system for B- and C-scan recording
sets the Explorer II apart from standard flaw detectors.
Control and Data Acquisition
Matec's MUIS32 software is as fast or faster than comparable DOS-based
systems. Our software is both modular and expandable design for
future upgrades with the ability to do both B- and C-scans. Post
analysis such as zoom, click on flaw and palette editing are standard
options.
