Why it matters
Electromagnetic fields from household wiring, routers, cordless phones and wireless technologies are invisible but measurable. Using a reliable meter gives you real data, rather than relying on guesswork.
Features & benefits
Measures three key field types: magnetic, electric and radio-frequency (up to 10 GHz) for broad coverage.
Equipped with a spectrum analyzer and data logging: captures high-speed digital RF pulses and stores data for review.
Compact, portable and user-friendly: it’s designed for both home use and field assessments, making it easy to test rooms, devices or wiring.
Alarm and visual alerts, to help you identify areas of elevated exposure quickly so you can take action.
1 year warranty
Ideal for
Homeowners (or soon to be) wanting to test EMF levels in bedrooms, living rooms, or near electronic devices.
Families or individuals who are sensitive to electromagnetic fields or pursuing a low-EMF environment.
Professionals, DIY auditors or health-aware users who wish to monitor 5G, Wi-Fi, smart meter or wiring emissions.
Anyone who wants to measure, understand and manage EMF exposure, rather than rely on assumptions.
