FNIRSI ERD-10 4-in-1 Electromagnetic Radiation Detector, Lithium-Ion Battery

The FNIRSI ERD-10 is a versatile 4-in-1 electromagnetic radiation detector designed for precise environmental monitoring. Powered by a rechargeable lithium-ion battery, this device effectively measures electric fields, magnetic fields, radio frequency (RF) fields, and temperature to ensure safety in residential and professional settings. Its compact design and intuitive interface make it an essential tool for detecting radiation levels accurately and reliably.

Advantages

This device offers comprehensive monitoring capabilities by combining four measurement functions into a single portable unit. The integrated real-time curve feature allows users to visualize radiation trends as they happen, while the dual-theme display ensures clear readability in both bright daylight and dark environments. Safety is enhanced through a multi-faceted alarm system that utilizes visual, audible, and LED flash alerts to provide immediate warnings when radiation thresholds are exceeded. The unit is designed for convenience with adjustable settings for volume and brightness, a data hold function, and an auto-off feature to preserve battery life.

Suitable for

• Monitoring electromagnetic radiation from household appliances like microwaves, refrigerators, and televisions
• Detecting radio frequency signals from WiFi routers and 5G networks under 3 GHz
• Assessing radiation levels near computers and power lines
• General environmental safety checks in homes, offices, and vehicles

When it may not be suitable

This device is intended for general environmental monitoring and is not a substitute for professional-grade industrial safety equipment or certified laboratory testing instruments. It may not provide accurate readings for high-frequency signals exceeding 3 GHz or specialized medical-grade radiation detection requirements.

Key specifications

• Measurement types: Electric field, magnetic field, radio frequency (RF) field, and temperature
• Display: Real-time curve visualization with day and night modes
• Alerts: Visual, audible, and LED flash alarm
• Power source: Rechargeable lithium-ion battery
• Dimensions: 68 mm width, 143 mm height, 29 mm depth
• Additional features: Data hold, adjustable volume and brightness, auto-off, and firmware update support

How to use

To begin using the detector, ensure the lithium-ion battery is fully charged. Power on the device and select the desired measurement mode to begin scanning your environment. The screen will display real-time data, which can be tracked via the curve function. If radiation levels exceed the set limits, the device will trigger the visual and audible alarms. You can adjust the display brightness and sound volume through the settings menu to suit your current environment. Use the data hold function to freeze a specific reading for easier documentation.

What to consider before purchase

• Verify that the frequency range of the devices you intend to monitor falls within the detector's operational capabilities
• Ensure the device is charged periodically to maintain readiness for environmental checks
• Consider the need for firmware updates to keep the device functionality current

Usage recommendations

For the most accurate results, hold the device steady and keep it at a consistent distance from the source of the electromagnetic field. Avoid blocking the sensors with your hands or other objects during measurement.
