How to contact Coltraco Customer Support?
If you have any questions please email support@coltraco.co.uk. When returning equipment please, follow the instructions found in this PDF.

Calibration Services
Why do you need to calibrate? Like an annual MOT on your car, calibrations service your equipment to ensure it is as accurate and reliable as when you first purchased it.

How often? In accordance with ISO 17025 for testing and measuring equipment, annual recalibration is recommended for companies complying with this regulation. Whilst there are some companies who offer 5 years calibration certificates, Coltraco Ultrasonics believe that we should follow the guidance set out in the regulations and thus offer 1year calibration certificates.
Where can you calibrate your unit?

Calibrations must be conducted in a Coltraco approved centre: either with us in the UK at the above address or with our ODA (Organisational Delegated Authority) Service Centres overseas.

How long will it take? We will always ensure that the turn-around-time is as short as possible. We aim to have the unit returned to you within a maximum of 10 working days, no matter where in the world our customers are. If required, replacement loan units can be made available for the duration that your unit is away for recalibration.

Spare Parts
If one of your ancillary items such as a sensor, receiver, generator or another part has been damaged, we have all of these parts available in stock and will be happy to supply these as required usually shipped door-to-door within 48 hrs.

User Training Support
The equipment is designed to be easy to use. Most users become competent quickly and easily, simply by following the Operating Instructions included in the ready-to-go packages.

However, if more training is required, we are happy to offer one-on-one tutorials. These are usually carried out over the phone/video call with one of our technical team. We take you through our Competency Compliance training to ensure you are confident in testing.
If you are a user of the Portascanner® and Portalevel® MAX – ultrasonic level sensor, we have online Interactive Training - see Training.

If your unit has been damaged whilst operating, we can repair it for you. Factory level repairs for the electronics; display module and membrane control panels have to be carried out in our facilities in the UK. Time scales for unit returns may vary depending on the severity of problem. If your unit has been damaged please contact our Support Department with a brief description of the problem and we will organise this for you as quickly as we can.

Upgrades & Trade-In Credits

Coltraco Ltd is always appreciated for being welcoming to all its clients across the world. Its mission to create accurate, reliable and easy to use instrumentation enhances the safety management of clients. The issue is not just about compliance with the regulations; it is about the safe ship offshore and the safe site onshore. This helps Coltraco’s clients to ensure lower risk, higher protection and business continuity for they believe in safety for safety's sake.

Ultrasonic Hatch Cover Testing

The hatch cover tester is a used onboard bulk carrier for inspecting the Watertight or Weathertight hatches for leak sites. The magnetic generator can be positioned just inside the hold, on the hatch combing, removing the need to climb down to position the generator at the bottom of the hold on the tank top. It is used by the crew for regular maintenance to dramatically reduce the risk of cargo damage from water ingress, and by Marine surveyors for carrying out P&I, Classification Society or Insurance surveys.

Watertight Compartment Doors Testing
Watertight Doors on offshore Oil & Gas Rigs, Naval and Marine Vessels are regularly inspected & maintained to ensure the integrity of the Bulkheads and watertight barriers are secure. If these areas are neglected, there can be drastic impacts on flood prevention in the event of a major incident, which is exactly what the Portascanner helps to avoid. Removing old fashioned and inaccurate chalk testing, the Portascanner Technology provides a very quick and accurate method to identify problem areas and fix the issues that exist within these seals.

Multiple Cable Transit Areas Testing

Cable Transit Seals provide a key element in maintaining the integrity of bulk heads and watertight seals onboard Naval, Offshore Oil & Gas and Marine assets. As one of the most neglected areas onboard, having the means to quickly identify the exact location and severity of issues in MCTs can dramatically assist Contractors and Fleet Operators to enhance the flood, fire & smoke protection that a correctly installed MCT seal provides. This device is regarded to be best for multiple cable transit areas testing.

Coltraco Ultrasonics has been in this field for more than 27 years whereas they are known to be the supervisor of this relevant field. The Portalevel® Standard uses ultrasonic technology to identify the interface between liquid and air in any single skinned container. It therefore has none of the user problems associated with radioactive liquid level indicators, which require dedicated training, storage, Health & Safety documentation, and transportation. It also replaces the traditional means of verifying liquid levels by dismantling and weighing in which the system may be closed down or disconnected, risking potential damage in so doing and involving considerable time, expense and inconvenience.
