How often should I calibrate?

We are often asked about calibration, why it is important, how often it should be done and why. The reason we know calibration to be important, and recommend its annual frequency is because our equipment is designed to improve safety and best practice. Ensuring the equipment used by crew/technicians/engineers to conduct such inspections is accurate and calibrated is a necessary one. Our manufacturer’s recommendations are based on the best that exist in ISO 17025 – an international standard for the calibration of any monitoring or measuring equipment: it must be at least once a year.

 Calibrating measurement instrumentation is vital for business continuity through improved maintenance procedures for all industries, yet the calibration of such equipment is not commonly discussed. All good companies will comply with calibration requirements, understanding the need to ensure their equipment works as designed. Yet negligence is commonplace due to lack of understanding of the value of calibrations and not knowing  the regulations.

But, what about 5 year calibration certificates? On calibration and as a manufacturer of quality, we are clear that it is unsound, unsafe and unprofessional to compete on calibration cost as some competitors offer 5 year calibration certificates. How can the manufacturer know its calibration will hold given the array of climate, humidity and environmental conditions that a product may go through 365 days per year ?  We wish to uphold the best there is in ISO 17025. Nor do we wish customers to believe that it is the manufacturer who dictates calibration standards, which is not the case – the key here is that we will not issue calibration certificates beyond a year.

 When you buy from any premier manufacturer, you have confidence in the longevity of your equipment, aided in our case by our Coltraco Customer Total Care Commitment, which includes life-time support. In addition, we have set up ODA Service Centres at major ports and centres worldwide, so our customers can send equipment for its calibration quickly and locally. We always do something “over and above” to enhance the unit for customers during its calibration and we have a wonderful reputation as a consequence.


CEO Message

Integrity and Science Key to Our Culture of Performance

Dear Coltraco Customers, Strategic Partners and Distributors,

Integrity is our defining value. Performance is its consequence. We understand that our customers have choices, and how we perform determines whether customers choose us. Coltraco’s Code of Ethics does not merely require compliance with laws. It embodies a Commitment to positive behaviours that build trust, promote respect, operate with distinction, with courtesy and global levels of performance, demonstrating our integrity and delivering customer performance.

We honour our commitments, communicate transparently, and act with honour. Ethics are the foundation of our performance culture and our science-based approach. We lead in specific technologies delivering the watertight integrity monitoring of marine structures and the monitoring of fixed liquefied gaseous fire extinguishing systems and the room integrity of protected space to ensure agent hold-times post-installation. We show this by our understanding of the science in them and the mathematics that explain them.

I would like to thank you for your business and for the relationships with our Customers, Strategic Partners, Distributors and ODAs who we value so highly.
