Multiple-Echo Ultrasonic Thickness Gage

(3 customer reviews)

The Cygnus 2 is a simple to use, through coating thickness gauge with a NEW high durability end-mounted rotatable LCD display making it ideally suited for climbing and rope access.

The twin shot injection moulded enclosure has a soft but durable TPE outer skin which is comfortable to hold and protects against bumps while the hard internal shell offers maximum strength and environmental protection certified to the demanding US MIL STD 810G standard.

Perfect for use on flat plate, curved surfaces or pipes our Multiple-Echo single crystal probe technology means you can measure through thick coatings and only the remaining metal thickness is displayed.

Cygnus Instruments builds all of its equipment in the UK using only genuine and original parts and components – including Lemo® Connectors and Peli® Cases.

3 reviews for Cygnus 2 Hands Free

  1. Rafael M.

    Believe it or not in the company that I belong to, we have an old one Cygnus 2 (single crystal) since 1990 or less, we compare to other devises that we have and confiability of Cygnus is incredible, there are certain surface that other can not measure. And our Cygnus has not the possibility to calibrate but when we test with the test block always is correct.

  2. Ben E.

    Haven’t had it long (9 months) but seems reliable and robust, despite being an older model (MK3)

  3. Fernando L.

    Cygnus 2 Hands free is very suitable for UT inspections at hullworks.
