The Selective Area Monitor AMS-8061 from Narda is always used where electromagnetic radiation levels need to be continuously assessed by means of long term observation. The AMS-8061 combines the latest technology with our renowned reliability: There are more than 3,500 in operation stationed around the world.

The AMS-8061 monitors high frequency fields from 100 kHz to 6 GHz with a three-axis isotropic antenna. This makes use of an analytical technique proven in Narda’s hand-held instruments. User friendly software allows individual definition and selective measurement of up to 20 frequency bands.

Additionally, its frequency selective application is the optimum solution for technical superiority from a tight budget. Narda EMF Monitors can do more than just record and save measurement values at a specific location. The AMS-8061 recognises which frequency bands and services are responsible for a particular radiation.

For example, if several antennas are installed at one location. It is possible to distinguish between the various mobile services (GSM, UMTS, LTE) as well as between FM TV transmitters. By the help of the built in spectrum analyser it is possible to determine for each individual EMF Source whether the corresponding emission limit values are being adhered to, in addition to evaluating the effects on the environment.

An internal modem is used for communications, ensuring compatibility with every data service worldwide. An automatic uninterrupted monitor gives a warning if any abnormalities occur.

Narda EMF Monitors incorporate all the features needed for reliable, continuous assessment of electromagnetic fields: Autonomous, weatherproof, mobile, robust, and low running costs. Narda EMF Monitors provide companies, authorities, and mobile telecoms providers with powerful instruments for performing long term on-vise evaluations for their clients.
