Dear Valued Durridge Customer, it is with heavy hearts that today we are announcing the impending discontinuation of the iconic RAD7 Radon and Thoron monitor on July 1, 2026. Due to the dramatic cost increase of the parts required to make the RAD7, coupled with our successful launch of the next-gen RAD8 Radon and Thoron Monitor, we felt it was time to embrace to the future of radon and thoron monitoring with our state of the art RAD8.
What if I own a RAD7?
Not to worry! Durridge plans on maintaining our ability to service RAD7s for as long as we are able. We have planned for this transition and have parts on hand from customers that have taken advantage of our RAD7 trade-in program when upgrading to a RAD8
What is this “Trade-In Program” you speak of?
Great question! Durridge offers RAD7 users the ability to trade in their old RAD7 units for a rebate towards a new RAD8. Discounts may vary based on the state and last calibration of your RAD7. Please contact the supplier you purchased your unit from for details, or if you bought from Durridge please contact us directly at
Request your RAD7 Trade-In Quote and upgrade to the RAD8 today!
