FNIRSI ERD-10 Electromagnetic Radiation Meter

Product detailed description

The FNIRSI ERD-10 is a portable 4-in-1 multifunctional electromagnetic radiation detector designed for monitoring home and work environments. The device measures electric field (EF), magnetic field (MF), radiofrequency radiation (RF), and ambient temperature.


Product parameters:

- 4-in-1 measurement: combines sensors to detect radiation from household appliances (microwave, TV, computer) and wireless signals such as Wi-Fi and 5G (up to 3.5 GHz).
- Display: 2.4-inch color TFT display with adjustable brightness. Supports curve mode for real-time monitoring of radiation trends.
- Warning system: offers three types of alerts when limits are exceeded—visual (red screen/light), audible signal, and vibration. Alarm thresholds are adjustable (default: 40 V/m for EF, 0.4 µT for MF).
- Power: built-in 1000 mAh battery with USB-C charging.
