Gigahertz Solutions ME 3030B LF EM radiation tester

This easy-to-use combination instrument makes professional measuring techniques available for home use. The only instrument in this price range to detect both mains current (50 Hz) and the frequency of overhead railway power lines (particularly important environmentally), which can often be detected several kilometres away from railway lines. The natural harmonics of mains current, e.g. from transformer stations, are also accurately detected. Another unique feature is the high resolution, which allows meaningful comparisons with the strict environmental limits.
