Tritex NDT Ltd

Ultrasonic & Underwater Thickness Gauges

Tritex NDT are manufacturers and suppliers of Ultrasonic Thickness Gauges.

ADC Member

Our range of Multiple Echo Ultrasonic Thickness Gauges are used extensively to measure the thickness of metals from one side only without the need to remove any protective coatings. They are also used to check corrosion levels on various equipment such as tanks, underwater equipment and pipelines.

At Tritex NDT we have used our wealth of experience and unique understanding of this technology to develop a range of products for a wide range of applications. It is only by understanding the problems and challenges clients face in these situations that enables us to provide them with the best possible solution.

Tritex technicians have applied this knowledge to designing and manufacturing a range of ultrasonic products that can be used to check and measure metal thicknesses without the need for coating removal which can sometimes result in costly replacements.


All Tritex Multigauges are manufactured to comply with BS EN 15317:2007 which covers the verification and characterisation of ultrasonic thickness measuring equipment.

Multigauge 3000
Multigauge 3000 Underwater is simple, and robust and designed for most common underwater thickness gauging applications.

Multigauge 3100
The Multigauge 3100 Surface Display Unit can be used with the Multigauge 3000 and offers a display at the surface to indicate the measurements the diver below is getting by either a class surveyor or supervisor.

Multigauge 4000
The Tritex Multigauge 4000 ROV is designed to be mounted onto all types of work class ROVs and is available in two models, for different depth levels.

Multigauge 5500
The Multigauge 5500 Waist which mounts onto a belt or chest harness to allow hands free use.

Multigauge 5600
Our Multigauge 5600 Hand Held ultrasonic thickness measuring device provides on screen user information such as probe frequency and battery remaining time.

Multigauge 5700
The Multigauge 5700 Datalogger has all the same features of the Multigauge 5600 but with the added advantage of storing measurements within the gauge. Templates can be created to store readings in a grid, string or combination of both, allowing complete versatility for many applications. Data is transferred from the gauge to the PC using a wireless RF transceiver. Intuitive menus ensure setup is extremely easy whilst the bright LCD display can be used in all light conditions.

Multigauge 5650 Surveyor Thickness Gauge
The multigauge 5650 is designed for small craft and ship surveyors. To cover all requirements the 5660 is capable of single echo, echo to echo or multiple echo.

Multigauge 5750 Surveyor Datalogger
The 5750 model is a simple and robust ultrasonic thickness gauge designed for small craft and ship surveyors. It has multiple echo modes to suit all requirements, has an echo strength indicator and comes with intelligent probe recognition.

Multigauge 5300 GRP
The Multigauge 5300 GRP is designed to check the condition of engineering plastics or glass reinforced plastics. It can however be used on various uncoated metals and comes with wireless data transmission.

Multigauge 5350 GRP Datalogger
The 5350 is the next step up from the 5300, measurements can be stored on the gauge and wirelessly transferred to a PC from up to 1000m away.

Multigauge 6000 Drone Thickness Gauge
The NEW Multigauge 6000 mounts directly on to a UAV or Drone with all measurements transmitted wirelessly in real time up to 500 metres away. Its lightweight and comes with a plastic probe to further reduce weight.

NEW - Multiguage 6500 Drone
The new Multiguage 6500 drone is a 'flying thickness guage' that includes the Multiguage 6000. It has been designed as a complete safe solution to check high level corrosion in out of reach places. Stops the need for rope access or scaffolding.

Tritex NDT also offers a range of software to display measurement results from the Multigauge 3000 or the Multigauge 4000. It can also be used to store measurements in a string, grid or a combination of both.


Tritex are always on hand in case of any questions or problems you may encounter, and you can contact us either by phone or e-mail. We will always do our best to make sure your gauge is always working to optimum performance levels.

Ian Bolderson, Marine Inspection Services

We have been using the Multigauge 5500 in some very poor conditions here in Poland....rough steel, hot conditions & a really dusty environment & it is performing excellently. Tom does not like using the 'other' manufacturers gauge!!!”

Jonathan Wamsteker, Sonometric

Tritex gauges are the best thickness gauges I have used (that exclude the paint) and they are less expensive than other makes that come close
