Origins
Established in 1971, Delta-T specialises in instruments for environmental science, in particular: agronomy, plant physiology, eco-physiology, data logging, meteorology, soil moisture, solar energy studies and environmental monitoring. Delta-T is a co-operative company, owned and managed by the members who work within it. Co-operative working creates an environment in which we all participate in the challenges of the business and benefit from its success. We share a high level of commitment to the company and to our customers.
For further information about the principles that underpin co-operative enterprises please visit the web site of the 
International Co-operative Alliance. 
High Quality Products
Delta-T's instruments measure and record basic variables needed by scientists and engineers. Our policy is to continually improve and extend the capabilities of those instruments, using the most up to date theory and technologies. Our experienced development team achieves a high rate of design innovation. Some projects are completely in-house, but others take the form of collaborative projects with leading institutions in many countries. 
Complete Systems
Our capabilities go beyond straight-forward instrument sales - we can also supply whole systems, including computers if required. Typical examples are automatic weather stations and logging systems for multi-point soil moisture measurement. 
Support
Delta-T has retained thousands of loyal customers all over the world who value the reliability, performance and long-term service that we provide. Their feed-back is incorporated into many product designs to create a process of continuous improvement. 
Overseas Representation
Delta-T has an international network of representatives who can provide local sales and service in most countries. Export sales account for more than 75% of Delta-T's business and we pride ourselves on the high standard of support given to our overseas customers.
