Happy with the quality and accuracy

My husband, a home inspector, who is certified by AARST (American Association of Radon Scientists %26 Technologists), is often asked to determine RADON levels in homes being purchased, or by Clients wishing to monitor performance of existing Radon Mitigation. He has in the past used the Safety Siren 3 which has been replaced by this Safety Siren 4. When he tested the 4 model, it performed well and the readout accuracy agreed with readings provided by more sophisticated "professional grade" test devices.
