Narda Area Monitors are used to verify the safety and environmental compatibility of electromagnetic fields (EMF). The devices are used wherever electromagnetic radiation has to be continuously assessed by long-term monitoring. The electric and/or magnetic field strength is measured and automatically compared with the limit values defined by national or international bodies as standards or guidelines. Narda offers various long-term measuring stations and measuring systems for this purpose, which are precisely adapted to the respective requirements, for example for outdoor use.
