Product Description

Durridge RAD7 Radon Detector is truly flexible radon and thoron detector used by research scientists and experts worldwide. Its mature yet still state-of-the-art design surpasses those of the most expensive radon measurement tools in the world. The device comes with a built-in air pump, rechargeable batteries, and a separable wireless printer. This Digital Radon Detector can store large quantities of radon data for later printing and for graphing and analysis.

The RAD7 is a Sniffer that identifies the 3-minute alpha decay of a radon particle, without intervention from other radiations. It also recognizes the instantaneous alpha decay of a thoron daughter for a fast thoron measurement. The Digital Radon Detector can sniff for access points and radon gushers, and it regains from high radon exposures in minutes. The RAD7 also works as a  Continuous Radon Monitor and can measure the EPA action level of 4 pCi/L, with a 10% average deviation, in under two hours. The detector prints out a complete report at the end of each run.
Features of Durridge Radon Detector:

  • Processes EPA action level of 4 pCi/L in less than two hours.
  • All-in-one complete, compact, portable unit in a tough holding case.
  • The device commands you step by step, so you can do what you want to do.
  • Programmed set-ups for often-used tests.
  • Audible radon and thoron counts let you hear the hot spots.
  • Easily transportable: The RAD7 weighs up to 4.35 kg.
  • Radon data is displayed, printed, and downloaded in your selection of units.
  • This Durridge RAD7 Radon Detector has Resistance to a build-up of 210pb.
  • RS-232 port and USB adaptor assure flexible connectivity.
