Overview
The FNIRSI ERD10 is a professional-grade Electromagnetic Field (EMF) detector designed to help you understand and minimize your exposure to electronic radiation. In a world full of 5G, WiFi, and high-power appliances, the ERD10 provides clear, real-time data across three critical spectrums: Electric Fields (V/m), Magnetic Fields (μT/mG), and High-Frequency RF (mW/m²). With its high-definition color screen and graphical trend tracking, you can pinpoint the exact source of radiation in your home or office.
Key Features
- 3-in-1 Comprehensive Detection: Measures low-frequency electric/magnetic fields (appliances, power lines) and high-frequency RF (WiFi, cell towers).
- HD Color Display: Large screen showing current values, peak values, and live radiation trends.
- Smart Alarm System: Traffic light indicator (Green/Yellow/Red) with audible alert when levels exceed limits.
- Peak Value Hold: Captures the highest detected value—useful for intermittent spikes.
- Sleek & Portable: Compact, ergonomic design with rechargeable battery.
