About Durridge
Durridge is a leading provider of professional radon detection equipment. Since 1997, Durridge has offered world-class radon detection solutions for businesses, universities, and governments worldwide. Our RAD8 and RAD7 continuous radon gas monitors feature precise measurement far exceeding EPA accuracy standards. Durridge also provides a wide range of accessories for the RAD8 and RAD7, as well as Capture software for performing sophisticated radon data analysis, and expert calibration and maintenance services.
The RAD7 electronic radon detector was invented by Professor Lee Grodzins when he was head of the radon program at the Massachusetts Institute of Technology. Durridge was formed in 1997 to take over production and support of the RAD7. Since then the RAD7 has continued in uninterrupted production and development, becoming an industry standard for research and professional applications. Today thousands of RAD7s are deployed worldwide, and the all-new RAD8 reimagines scientific-quality electronic radon monitors with complete top-to-bottom upgrades.
