This is a professional compact meter that measures AC electric and AC magnetic fields in the frequency range between 5 Hz and 400 KHz. It features an extended frequency coverage, increased sensitivity, and a switchable frequency filter for identifying the radiation source.

Availability: Usually ships in 1 to 3 business days




The Gigahertz Solutions ME3951A Low Frequency Analyser can measure frequencies ranging from 5 Hz to 400 KHz and is well suited for professional applications such as scientific and industrial purposes. It measures low frequency fields from sources such as electrical wiring, power lines, transformers, and household appliances, and its extended frequency range allows it to detect higher frequency ranges from newer technologies. Its built in switchable frequency filter helps in identifying the radiation source.


- 5 Hz to 400 KHz frequency range
- Boasts a 98% accuracy
- Detects low frequency electric and magnetic polluters, including electrical wiring, power lines, transformers, and household appliances
- Built in frequency filter provides three filter settings to isolate frequency clutter and allow for source identification
- 2 year manufacturer's warranty
