Lutron 3 Axis EMF Radio Frequency Radiation Meter. Model EMF-819.
The EMF-819 is a 3-axis RF electromagnetic field meter designed for measuring radio frequency (RF) radiation strength across a broad frequency range of 50 MHz to 3 GHz. Equipped with a high-frequency probe, it provides precise electromagnetic field (EMF) readings in units of V/m, W/m², and mW/cm². The meter features an alarm setting function, data hold, peak hold, and an RS232 interface for data transfer, making it ideal for monitoring EMF exposure from cell towers, radar, microwave ovens, and other RF sources.
