Specialists in Gas Analysis Techniques

For nearly 30 years Gas Data Limited has designed and developed specialist gas analysis techniques. Experience is at the heart of the Gas Data’s range of gas monitoring and analysis equipment.

Business Approach

Working closely with clients, Gas Data make sure that everything is thoroughly understood and what the critical measurements to be made are, and under what conditions; the more that is known, the better the client is accommodated.

Gas Data match or modify technologies and products to the client’s requirements; offer and explain the complete solution to the customer; deliver and verify the solution to the client’s satisfaction.

Fully Accredited

Gas Data is licensed to manufacture ATEX certified gas monitoring equipment and is ISO9001:2015 accredited. All products must pass specialised testing procedures before they are delivered to clients.

Ongoing Support

Purchasing Gas Data products is only the beginning. Comprehensive maintenance options are available to ensure that clients continue to empower environmental evolution.

No matter the age of the instrument, Gas Data will continue to service it, as long as the technology is available!

Gas Data has clients about to enter their third decade of operation; a testament to the longevity of the instruments and an important reason an ever-growing Gas Data client base choose to remain loyal.
