About Us

CODEL International Ltd, a UK-company based in Bakewell, in the heart of the picturesque Peak District National Park, design and manufacture cutting edge instrumentation, primarily for monitoring emissions to atmosphere, road tunnel environments and plant and rail safety.


The company was initially formed in 1982 to design and manufacture gas monitors for process control use. Over the years the increase in environmental issues and new international legislation has guided our research and development department to continually improve and increase our product range.

Today our state of the art analysers are supplied to a wide range of industries worldwide including power generation, combustion processes, road tunnels and process control.

Our products form a wide range of instrumentation from dust monitors through to fully automated and integrated emissions monitoring systems.
