FNIRSI ERD-10 is a portable 4-in-1 EMF detector for quick, easy-to-understand measurement of the electric field (EF), magnetic field (MF), RF radiation (Wi‑Fi/Bluetooth/mobile networks), and temperature. It features a 2.4" color TFT display, a real-time graph, adjustable alarms, a HOLD function, and USB‑C charging—ideal for home and office.
The FNIRSI ERD-10 detector helps you easily check electromagnetic radiation levels in everyday situations—near a Wi‑Fi router, household appliances, a laptop, a phone, or electrical wiring. By combining four measurements in one device, you get a fast overview of your environment without complicated setup.
The large 2.4" color TFT HD display is easy to read day and night. It offers a light and dark mode and adjustable backlight brightness. The curve (graph) mode clearly shows how values change over time, making it easier to identify sources of increased emissions.
For extra peace of mind, the ERD-10 includes smart alarms (visual, on-screen, and vibration/sound) with user-adjustable thresholds. The built-in 1000 mAh battery and USB‑C charging make it convenient at home and on the go. Also useful are the HOLD function to “freeze” the measured value and auto power-off to save energy.
