VisZelie measures three distinct electromagnetic radiation types simultaneously: Electric Field (EF) in V/m, Magnetic Field (MF) in mG or µT, and Radio Frequency (RF) in mW/m². This covers everything from power lines to Wi-Fi routers.

Yes. It features a high-precision micro-controlled chip processor with an accuracy of ±5% and a wide bandwidth of 50Hz to 3500MHz. It is used by home inspectors, environmental assessors, and maintenance staff.

The 3-level alarm system handles this for you. 'Safe' levels show green alerts, 'Alert' levels trigger yellow/sound warnings, and 'Avoid' levels (EF >80 V/m, MF >8 mG, RF >10 mW/m²) trigger high-intensity light and sound alerts.

Yes, the RF detection mode is highly sensitive (0.01 mW/m²) and covers frequencies up to 3500MHz, making it ideal for monitoring signals from 5G towers, cell phones, and smart meters.

The VisZelie detector is powered by a standard 1× 9V battery (not included). It features an auto-shutdown mode after 15 minutes of inactivity to preserve battery life, though this can be disabled for continuous monitoring.

Not at all. It was designed with large backlit digits and clear, tactile rubber keys. You simply turn it on and measurements appear in real-time. The alarm system tells you when to be concerned so you don't have to memorize scientific thresholds.
