FNIRSI ERD-10 4-in-1 EMF Meter — Electric, Magnetic & RF Field Detector

FNIRSI ERD-10 4-in-1 EMF Meter The FNIRSI ERD-10 is a handheld electromagnetic radiation detector that measures electric field strength, magnetic field strength, radiofrequency power, and temperature. A 2.4-inch color screen shows live readings, making it suitable for surveying homes, offices, vehicles, and outdoor environments. What it measures Magnetic field: 0.01–99.99 μT (accuracy 0.01 μT, alarm at 0.4 μT) Electric field: 1–1999 V/m (accuracy 1 V/m, alarm at 40 V/m) RF power density: 0.2–1000 mW/cm² Environmental temperature Hardware 2.4" color screen with adjustable backlight 1000 mAh battery, USB Type-C charging (5V/1A) ≈143 × 68 × 29 mm, ≈143 g; auto-shutoff (off / 5 / 10 / 15 min) In the box: ERD-10 meter, Type-C cable, user manual This is a measuring instrument, not a shielding product — it detects and displays field levels so you can survey your environment. It does not block or reduce EMF, and readings are for general awareness, not medical assessment. Explore more: Faraday bags · RFID protection · EMF & RF detectors.
