A selective radiation meter (SRM) takes measurements and can immediately produce results without additional cables and without an external PC.
With an isotropic probe, the SRM is battery powered and immune to interference. It eliminates the need for specialised scanning techniques.
The SRM evaluates the field strengths it measures in accordance with relevant regulations in a format that highlights field strength levels, single source or single channel, contribution by a particular telecom service, contribution by all services and their percentage of the total exposure.
Depending on the probe used, suitable applications include fast, isotropic measurements on radio systems (e-field probe, isotropic) and precision measurements in the VHF band (e-field probe, dipole). Using the probe, the SRM works in the frequency range from 80 MHz to 3 GHz, covering all services from FM radio to UMTS.
The SRM, designed especially for safety in electromagnetic fields, is sensitive enough to measure individual GSM channels inside buildings and verify limits as low as a few volts per metre in sensitive areas.
It is also capable of measuring field strengths in the immediate vicinity of a powerful medium wave transmitter and has an RF immunity up to 1000 V/m.
