Multigauge 3000 Underwater Thickness Meter

The Multigauge 3000 Underwater Thickness Meter is designed to be used by a diver for most common underwater thickness gauging applications. It is a simple, robust, hand held meter which uses Multiple Echo to ignore coatings, measuring only the remaining metal thickness.

The Multigauge 3000 Underwater Thickness Meter is a simple, robust ultrasonic thickness gauge designed for most common underwater thickness gauging applications. The meter is pressure tested to 500m and has the option to transfer measurements to a Surface Display Unit or Communicator Software with the simple addition of a replacement end cap. It has been designed and built to survive extremely harsh conditions that exist in the offshore and underwater industries worldwide.  The gauge uses multiple echo which means measurements can be easily taken without the need to remove coatings, up to 6mm thick, and the large bright LED display ensures the display can be seen by the diver, even in poor visibility.

The Multigauge 3000 Underwater Thickness Meter is equipped with Intelligent Probe Recognition (IPR), which automatically adjusts settings in the gauge for enhanced performance and Automatic Measurement Verification System (AMVS) to ensure only true measurements are displayed, even on the most heavily corroded metals. Only one single crystal probe type is required for all gauging applications. The meter is supplied as a complete kit ready to use out of the case, with a 3 year warranty and free annual calibration for the life of the gauge.

SeaTech Commercial Diving Services Ltd - United Kingdom

“ We have a lot of experience using underwater thickness gauges but my team insist on using only the Tritex gauges now. The Multigauge 3000 gives stable measurements and locks onto readings instantaneously"

Valkyrie Diving - United Kingdom

“The Multigauge 3000 is absolutely brilliant, we love it! If there was any problem we would tell you. Also, the service is excellent!”

Harbour & Marine Diving Contractors Ltd - United Kingdom

"The gauge gives quick and accurate readings, requires far less surface preparation than other makes we have used and locks on much faster. it can speed up the survey process by a factor of at least two."

Niras - Denmark

"As a diver and engineer I am very satisfied with the Tritex gauge......especially because the Tritex is easy to use and easy maintenance."

Performance Marine - Vanuatu

"We use a multigauge 3000 from Tritex UK. Great results and backup."

Transport & Technical Services - Jersey

"The gauge is light, simple to calibrate and above all very accurate. When not being utilised underwater the equipment is used for other types of thickness monitoring around the Ports with great success. A final point to note is that even the Divers like working with it and we all know how hard they are to please!"
