Sonatest Masterscan 700m





The Masterscan 700M offers the end user a high end narrowband flaw detector with a full VGA display, sync and proportional outputs, sync input and a Spike and Square pulser. Features like high levels of near surface resolution, penetrating power (450V pulser – square and spike) and excellent signal to noise ratio, can be added and upgrades performed in the working environment, reducing downtime and increasing working flexibility. The Masterscan 700M’s enclosure is constructed using impact resistant materials and is designed to meet IP67 standards, offering excellent water resistance and harsh conditions. Typical applications are Weld Fabrication, Corrosion Detection, Composite Inspection, Bond Testing, Forgings & Castings, Power Generation (including EMATS) and general UT inspection.

Reject (Selectable): Up to 80% Linear reject (removes baseline noise without affecting indication amplitude) or Up to 50% Suppressive reject (increase zero offset and reduces amplitude of all echoes).
LED Warning when active.

Gate Monitor: Two independent gates for measurement and monitoring. Start and width fully adjustable over the entire range of the instrument. Levels adjustable from 0% to 100%, positive or negative triggering on each gate with audible & visible alarms. Gate resolution is 5Ns.
Zoom: Expands range and delay to cover the area set by Gate 1 start & width controls.
AGC: Automatic Gain Control automatically sets the signal in Gate 1 to a level between 10% and 90% FSH, tolerance between 5% and 20%.
Contour: Trailing-Edge-slew-rate control to reduce half cycles in rectified modes. Selectable from one of 6 levels.
Waveform Smoothing: Select from

  1. None (both min and max values are displayed in the A-Scan)
  2. Fill (Min values set to baseline value, produces a solid A-Scan)
  3. Smooth (min values ignored, produces a clear outline A-Scan)
Persistence: Causes previous A-scans to “fade out” at a user-determined rate
Auto-Cal: Provides automatic calculation of velocity and probe zero from 2 reference echoes.
Reference Waveform: Displays a previously stored A-log in a color different from the active display, enabling a quick visual check of the differences.
Clock: Built in, battery-backed RTC keeps time and date. Visible on the status line, always stored with Panels, A-logs, etc.
