Curious about the invisible radiation around you? This Fovolat EMF detector lets you measure both electric and magnetic field radiation in your environment. For electric fields, it measures from 1 V/m to 1999 V/m with 1 V/m accuracy and alarms at 40 V/m. For magnetic fields, it ranges from 0.01μT to 99.99μT with 0.01μT accuracy, alarming at 0.4μT. You can switch between temperature units (°C/°F) and magnetic field units (μT/mG) depending on your needs. The handheld design makes it super portable - perfect for carrying around your home, office, or even for paranormal investigations if that's your thing. It features sound and light indicators that alert you when radiation levels exceed safe values - the alarm sound actually gets stronger as radiation increases. The green ABS PP construction measures 22x6x5.5cm and operates on three AAA batteries (not included). It samples every 0.4 seconds with ±15% accuracy and works in temperatures from 0-40°C (32-104°F). You can test household appliances like TVs, computers, refrigerators, induction cookers, rice cookers, cell phones, and electrical wiring to see what's emitting radiation around you. The interface is straightforward with one-hand operation - no complicated settings to figure out. Whether you're concerned about EMF exposure for health reasons, want to identify sources of interference, or are into ghost hunting as a hobby, this detector gives you actual data instead of just guessing. It's a secondary analytical tool for parapsychological research, but honestly, most people just want to know if their bedroom has high EMF levels from that power strip behind the bed. The low voltage prompt at 6.8v lets you know when batteries need changing, and the overall build quality feels solid for the price.
