Welcome to Gradko Environmental - Air Pollution Monitoring Equipment

Passive monitoring technology provides low-cost long-term air sampling over a large area without the need for capital investment, infrastructure or a power supply. Its simplicity aids its versatility.

Our products are now available for a wide range of pollutants and our research into new equipment or applications is ongoing, with the recent addition of our Rapid Air Monitors for very short-term passive sampling.

Gradko is based in Winchester, UK, providing manufacturing and global distribution of our air monitoring products. Our dedicated laboratory is UKAS accredited (ISO: 17025) and provides accurate and timely analysis of our customers samples.

We were pioneers in the development of passive diffusion tubes (Palmes Tubes) in conjunction with the UK Government Department of Trade and Industry. Over the subsequent 20 years our success has been built on providing a progressive, flexible and cost effective service. The technical knowledge acquired during the development phases enable us to provide a comprehensive technical back-up service. This, combined with customer driven quality objectives, provides an ongoing path to excellence in all that Gradko Environmental sets out to achieve.
