Negative Positive
Title: Confirmed By Test
Review: We purchased this unit and got high readings so we contacted a radon test company. They ran their test and the numbers came in right on the button with our Safety Siren Pro Series 3. Mitigation was done and a follow up test was performed by the testing company. (Testing and mitigation were done by two separate companies to avoid any conflicts) Now our always-on Safety Siren Detector provides a consistent way to visually check the current readings and also will provide an audible warning if the levels ever get too high again. Our mitigation system has only a visual method of checking operation and it's nice to have the audible backup of the Safety Siren.
