Leaders in professional radon instrumentation and analysis solutions

DURRIDGE is a leading provider of professional radon detection equipment. Since 1997 DURRIDGE have offered world-class radon detection solutions for business, universities, and governments worldwide. Our RAD7 continuous radon gas monitor features precise measurement far exceeding EPA accuracy standards.

The RAD7 is the best commercially available instrument for measuring Rn that I have ever seen. We originally bought one - we now own 12 and may purchase more.

DRYSTIK ADS-2 Pump Upgrade
The Durridge DRYSTIK ADS-2 active moisture exchanger has been updated with high quality pumps, available in brushed and brushless varieties. With the improved pump the DRYSTIK ADS-2 will perform flawlessly for years to come. Existing DRYSTIKs may be returned to us and we will upgrade them to new pumps with a quick turnaround time. The DRYSTIK ADS-2 removes moisture from air entering the RAD7, greatly extending desiccant life. Learn more at the DRYSTIK ADS-2 page.
