  • Lightweight, ergonomic, rugged design- including anchor points, topside connector panel, pipe stand, and tripod mount
  • Thumbwheel option for rapid menu navigation
  • Toughened, anti-glare, crisp, daylight readable display, with screen protector
  • A single and dual frequency range of 10Hz-20MHz, ideal for a wide range of applications
  • Designed to meet IP64, IP68 rated connectors
  • Over 7 hours battery life, fast 2.5 hrs charging time
  • Industry standard probe connectors

Software Features

  • Auto-Mix: simplifies the procedure of mixing two different frequency signals 
  • Innovative Loop Feature: 'Loop' is a convenient way of capturing live, repetitive signal and then adjusting the instrument settings; in particular, Phase, Gain, and Filters in order to simplify the task of optimizing the parameters
  • Guides: allow the user to display a slide show that is compatible with most presentation software native to desktops and laptops.
  • Trace: allows a reference waveform to be stored on the screen and appears along with the graticule behind the live spot. Allows the operator to compare live data with a reference calibration
  • Operator Defined Soft Keys: quick access, one-press functionality that is easily programmable to streamline user operations for specific applications


The AeroCheck 3 utilizes a wide frequency range (single and dual) of 10Hz to 20MHz, ensuring a diverse range of applications. Its wide frequency range is matched in capacity by the AeroCheck 3s Eddy Current Probe capacity, which includes Absolute, Bridge, and Reflection connected probes. 

  • Common Aerospace Applications Include:
  • Wing & Surface Hinges
  • Fuselage
  • Windows and Frames
  • Wheels, Wheel Brakes, and Landing Gear
  • Engine Blades & Discs
  • Horizontal Stabilizers
  • Door Access Points and Window Frames
  • Bulkhead Frames
