Both have been designed to operate in the harsh conditions of offshore and underwater industrial work. The products use multiple echo for easy taking of measurements while ignoring coating of up to 6mm thick. And the user-selectable RS422 or RS232 output means that connecting to ROVs is easy. The product has a single crystal soft-faced probe operates at 2.25MHz, 3.5MHz, or 5MHz, with a measurement range of 1mm to 250mm. Please visit our website for full product details.

Multigauge ROV Probe Holder

We offer the Multigauge ROV Probe Holder to accurately and delicately present an ROV-mounted measurement probe to the surface to be measured, whether curved or flat, in a way that maintains the integrity of the surface while avoiding any silt or seaweed clogging in the underwater environment. Our Probe Holder can be used with most types of ROVs. The product offers a 75-degree freedom of movement in all directions without any axial restriction. We build the Probe Holder from titanium for lightness and strength. Please visit our website for full product details.

Applications - Shipping

Monitoring corrosion levels is essential to the safe and efficient operation of ships. Our Multigauges can measure the thickness of metal – whether there has been any literal wear or tear – in even the most challenging of seafaring environments. Our probes can even be used on pitted surfaces to give a true thickness measurement from the bottom of the pit to the back wall of the metal hull.

Applications - Offshore

Offshore industrial work presents challenging environments that demand frequent metal testing and measurement with tools that are reliable and durable. Corrosion is a danger that must be monitored and our Multigauges are perfect for inspecting pipelines, ship hulls, cranes, cylinders, offshore platform risers, and oil rigs.

Applications - Rope Access

Our Multigauge 5500 can be mounted on to the chest harness of a rope access system – eliminating the need to wear the Multigauge from a belt or round the beck. This is an exceptional convenience in an otherwise physically and mentally demanding operational environment. The probe is there when you need it, suspended from the rope access harness, and can be tidily stowed when it is not in use.

Applications - Pipelines

Pipeline networks are one of the foundations of the global economy – oil, gas, and chemicals, are all transported from country to country through an extensive series of pipelines. Corrosion, environmental damage, and human harm are severe risks if pipelines are damaged. Our Multigauges allow operators to conduct ultrasonic thickness inspections on pipelines to avoid costly and damaging leaks.

Applications - Storage Tanks

Corrosion of storage tanks containing hazardous substances such as chemicals and petroleum can have calamitous results and therefore regular monitoring of the tanks is paramount to ensure potential accidents are avoided.  In particular, tanks that are used to store liquified petroleum gas (LPG) are particularly prone to corrosion and routine checks should be carried out to ensure thickness levels are at a safe level.  Tritex multigauges are a cost effective and easy way of conducting thickness checks accurately and our Multigauge 5500, with its belt clip, is particularly user friendly when working on ropes, ladders or scaffolding.

Applications - Lighting Columns

Corrosion at the base and collar joint of lighting columns is common as a result of ground water, condensation and splashes of water from passing vehicles.  As lighting columns are often in public places it is important they are regularly inspected to avoid any accidents caused by the column falling down and this is often undertaken by local governments.

Applications - Road Tankers

Routine inspections of road tankers is essential in order for potential accidents to be avoided and the use of thickness gauges is a highly effective and practicable way of conducting a corrosion assessment as tankers corrode from the inside. Our ultra sensitive gauges will discount any coatings and decals on the surface of the tanker and will allow you to measure the thickness of the metal only.

Applications - Bridges

Depending on the type, bridges are required to be inspected every 2 to 6 years to ensure they are fit for purpose and can continue to be used safely.  Titrex multigauges can be used to monitor metal thickness across the bridge structure, taking into account any surface rust that may be present from weathering.

Applications - General Industry

Many factories utilise tanks and pipelines for storing chemicals and also for moving them from one part of the site to another and these pipes and tanks are liable to deterioration over time and Tritex multigauges make monitoring the corrosion easy and cost effective.  Regular monitoring of the tanks and pipes will ensure early detection of corrosion, which left untreated, could result in devastating accidents.  Tritex multigauges are very versatile and can be used as a monitoring apparatus in a multitude of situations such as measuring boiler tubes, monitoring wear on machinery and the condition of plant asset, and can also be used for inspecting metal structures.

Applications - Underwater

All underwater structures, especially those in a sea water environment which are particularly prone to corrosion, should be subjected to regular assessment in order for early damage to be identified and treated.  Tritex’s Multigauge 3000 has been designed for taking accurate underwater thickness measurements for a wide range of underwater applications including pipelines, offshore platforms, ships, piers, bridges, pilings and lock gates.  The Multigauge 3000 allows divers to take accurate readings without removing any coatings on the metal in question and its large LED screen means measurements can be taken even when visibility is poor.

Other Applications

Aside from those listed above, our multigauges are suitable for using on any metal, as the nature of metal inherently means it is susceptible to corrosion.  Other applications include mobile phone masts, children’s’ playground equipment, gas cylinders, boilers and boiler tubes, trains, fairground attractions, surveillance camera masts, electricity pylons, windmills and quality assurance.  Please contact us to discuss the most suitable gauge for your requirements.

Technology

Tritex multigauges utilise multiple echo to measure the thickness of metals. The gauge transmits an ultrasound pulse which then penetrates the metal and any coating it may have on it.  This ultrasound is then reflected back and echos within the metal.  As the coatings will have a different velocity of sound to the metal only a small amount of the ultrasound goes back through the coating and this timing correlates to the timing of the echo in the metal and allows a measurement for the thickness of the metal only to be calculated.  The gauge works on an Automatic Measurement Veriftication System whereby a minimum of three readings are taken to ensure optimum accuracy.
