Cygnus 4

MULTIPLE ECHO ULTRASONIC DIGITAL THICKNESS GAUGE


  • Light, small and shock-proof within IP65 sealed aluminium housing
  • Gauge senses probe type and automatically adjusts settings
  • Valid thickness measurements and minimum thickness function
  • Deep-coat mode for coatings up to 20mm
  • Secure, twist-to-lock probe connection (BNC)
  • Simple keypad operation 


The general purpose Cygnus 4 is the most versatile through coating thickness gauge available and perfect for all lighting conditions.

Light and simple to use - yet accurate and very durable!

The Cygnus 4 is ideal for use on flat surfaces or pipes. The multiple echo single crystal probe technology means you can measure through thick coatings and only the remaining metal thickness is displayed.

  • Instrument
  • 2.25 MHz x 13 mm diameter probe
  • spare membranes
  • 15 mm steel test block
  • membrane couplant
  • ultrasonic couplant
  • accessory pouch
  • protective silicone sleeve with neck strap
  • operation manual
  • carry case
  • optional belt/harness clip
