FNIRSI ERD-10 electromagnetic radiation detectorThe FNIRSI ERD-10 is a modern, portable 4-in-1 electromagnetic radiation detector that combines the measurement of electric (EF), magnetic (MF), radio (RF), and temperature fields in one compact device. It features a clear 2.4" TFT color screen, real-time graph mode, adjustable alarms, a built-in 1000 mAh battery with USB-C charging, and automatic shutdown. This tool is designed for homes, offices, and users who want to be mindful of their surroundings.4 in 1 – real knowledge about your environmentThe ERD-10 measures exactly what matters on a daily basis: the electric field generated by electronic devices, the magnetic field produced by household appliances, RF radiation emitted by Wi-Fi, Bluetooth, or smartphones, and the ambient temperature. With wide measurement ranges (up to 1999 V/m and 99.99 µT), you get a complete picture of the situation – no guesswork and no specialist knowledge required.Easy-to-read HD screen – comfort day and nightThe large 2.4-inch TFT color display ensures excellent readability in all conditions. You can switch between light and dark display modes, adjust the backlight, and use clear icons and large digits. The result? Instant data reading – even in a dark room or in bright light.Graphs and curve mode – see where the threat is coming fromRadiation is not constant, which is why the ERD-10 offers a curve mode that shows changes in intensity over time. This makes it easy to locate the source of the emission and check how strong it is at any given moment. This is a huge advantage over simple meters that only show a single value.Smart alarms – safety without monitoringThe device is equipped with three types of alarms: audible/vibrating, light, and screen. When the set thresholds are exceeded (default >40 V/m for EF and >0.4 µT for MF), the ERD-10 immediately alerts the user. Importantly, you can customize the alarm thresholds to suit your needs, giving you full control over the safety level.Ready for everyday scenariosCheck your Wi-Fi router, microwave, refrigerator, air conditioner, TV, laptop, console, or phone. The ERD-10 is designed for real-world home and office applications, making it ideal for parents, people who work with electronics, and anyone who wants to consciously limit their exposure to radiation.Built-in battery and USB-C – convenience without cablesThe 1000 mAh battery ensures long operating time, and USB-C (5V/1A) charging allows you to recharge from a power bank, laptop, or mains charger. The automatic shut-off function protects the battery and eliminates unnecessary power consumption when the device is not in use.Ergonomics and features that make life easierThe compact housing, comfortable grip, logical button layout, and HOLD function to freeze the result make it intuitive to use, even for beginners. The English-language menu, solid construction, and low weight (approx. 143 g) make the ERD-10 a practical everyday tool.A conscious choice for those who want to know moreThe FNIRSI ERD-10 is not a gadget, but a functional meter that provides real knowledge and a sense of control over your surroundings. If you care about the safety of your household, better working comfort, and reliable data, this device will quickly become an indispensable part of your equipment.Included: FNIRSI ERD-10 electromagnetic radiation detector USB Type-C cable User manual Manufacturer FNIRSI Model ERD-10 Device type 4-in-1 electromagnetic radiation (EMF) detector Electric field (EF) measurement range 1–1999 V/m Magnetic field (MF) measurement range 0.01–99.99 µT (0.1–1999 mG) Radio frequency (RF) measurement range 0.1–1999.9 µW/cm² Temperature measurement range 0–70°C Measurement modes EF / MF / RF / temperature + curve mode (real-time graph) Display 2.4" color TFT HD screen Display modes Bright mode (White Display) / dark mode (Black Display) Backlight Adjustable brightness Alarms Light / screen / vibration (3 types of alarms) Alarm thresholds User-configurable
