Jon Sharland recently gave a presentation at the IIMS Large Yacht & Small Craft Athens Training Event via video conferencing. The talk covered the technology behind multiple echo thickness gauges and new developments by Tritex NDT for the inspection of GRP in yachts and small craft. At the end of the technical presentation various gauges were discussed such as the new Multigauge 5650 Surveyor Thickness Gauge for steel and GRP measurements and the Multigauge 5300 GRP Thickness Gauge for just GRP measurement. A group of nearly 20 surveyors met in Greece with additional surveyors joining online for the conference.
We have launched our new Multigauge 5650 Surveyor thickness gauge. The new gauge, based on the already very popular original Multigauge 5600, has new features specifically designed for marine surveyors but the gauge can be used for other applications as well. The gauge can be used with existing standard soft faced probes for measuring metal thickness through coatings, up to 20mm thick, to give the same high standard of performance as the Multigauge 5600. However, by simply exchanging the probe, the gauge automatically switches to GRP measurement mode which uses single echo. This can be used to assess the condition of GRP when checking for osmosis and delaminations. Either probe can also be used in echo – echo mode, if required, by easily selecting the option from the keypad during measurement. No special probes are needed for echo – echo mode.
The gauge has a large modern colour display and an easy to use clear graphic menu. It has been designed in line with Tritex’s concept of Simple, Accurate and Robust. Intuitive menus allow for easy navigation whilst the gauge has added features to improve performance.
For metal measurement, the gauge utilises the Multiple Echo technique to ignore coatings up to 20mm thick and just measures the metal substrate. No grinding or removal of the coatings is required, significantly reducing preparation time and ultimately saving both time and money when carrying out inspections. All probes have Intelligent Probe Recognition (IPR), which automatically adjusts settings in the gauge when connected, resulting in a perfectly matched probe and gauge for enhanced performance. Also, the Automatic Measurement Verification System (AMVS) used with multiple echo ensures only true measurements are displayed, even on the most heavily corroded metals. An optional leather case protects the gauge in even the most harsh environments.
Only single crystal probes are used, which have a number of advantages when measuring on curved and corroded surfaces. The new Multigauge 5650 is supplied as a complete kit, ready to use, with a 3 year warranty and free calibration for the life of the gauge.
Tritex NDT are pleased to announce the launch of the new Multigauge 5700 Datalogger gauge which stores measurements on the gauge in a grid or string format. The results are then transferred to a PC or laptop using a RF transceiver. This means that the gauge can also be used for remote datalogging applications. The gauge has the same features and high level of performance as the Multigauge 5600 thickness gauge, but with the added benefit of being able to store measurements on the gauge.
Tritex NDT is pleased to announce a rental partnership agreement with Subsea Technology and Rentals (STR), a multi-disciplinary technology expert.
An array of Tritex NDT specialist diver and ROV equipment will now be available to hire or purchase through STR’s Head Office in Great Yarmouth, including The Multigauge 4100 and 4400 Underwater Thickness Gauges.
The Multigauge 4100 and 4400 are simple, robust ultrasonic thickness gauges designed to be mounted onto all types of work class ROV’s. There are two models in the range, the Multigauge 4100 which has a depth rating of 3280 feet and the Multigauge 4400 which has a depth rating of 13,123 feet. Both gauges have been designed and built to survive extremely harsh conditions that exist in the offshore and underwater industries worldwide. The gauges use multiple echo which means measurements can be easily taken without the need to remove coatings, up to 0.25”, and the RS422 output makes connection to most ROV’s simple.
Neil Jackson, Sales and Operations Manager at STR, said: “This agreement can only enhance our ability to provide advance technology fast. STR are keen to develop partnerships with manufacturers capable of offering the highest level of products, service and knowledge to benefit our customers across the globe.”

Due to increasing global demand for our product range, Tritex NDT have opened an office in the United States as part of an ongoing strategy of expansion. The new office, based in Newark, New Jersey is ideally situated to better serve our customers in North and Central America, including Canada. Tritex NDT have taken this initiative to offer our multiple echo ultrasonic thickness gauges into these regions while providing better customer service. The new office will provide local product support as well as sales and marketing operations. Tritex NDT LLC can be contacted here.
Tritex NDT have launched their new gauge, an upgrade on the already very popular Multigauge 5600 Multiple Echo Ultrasonic Thickness Gauge. The new model features a large modern colour display with an easy to use clear graphic menu. The gauge has been designed in line with Tritex’s concept of Simple, Accurate and Robust. Intuitive menus allow for easy navigation whilst the gauge has added features to improve performance. The new Multigauge 5600 maintains robustness with the shock proofing rubber gasket surrounding the gauge.
The tanker RFA Darkdale was sunk by a German U-
A team of 9 people from the Ministry of Defence DE&S Salvage and Marine Operations (SANMO) were deployed to St Helena in April to investigate the exact condition of the ship and to ascertain whether RFA Darkdale is likely to become an environmental hazard to the island.
Part of the survey involved using a Tritex Multigauge 4100 ROV mountable thickness gauge mounted onto a Seaeye Falcon ROV. The gauge was used to inspect the corrosion levels and determine the amount of wastage that has occurred in the hull and whether there is any risk of the hull leaking any more oil.
Following the investigation, Mr Andy Liddell, one of the team members, said, “The gauge worked and we got readings off the hull, I have to admit to being surprised given the corroded state of the hull.”
Tritex NDT have developed a new probe holder for use with the Multigauge 4000 series ROV gauges. The ingenious design means that measurements can be taken at all angles, in any direction, with no moving parts which can get clogged with silt and seaweed. The new probe holder is made from Titanium for strength and lightness. The new simple and robust design was accepted with lots of enthusiasm at the recent Oceanology exhibition.
