Geiger Counter, Electromagnetic Field Radiation Detector with Automatic Alarm and Backlit LCD Display, Portable EMF Tester for Home and Office EMF Inspections

[Portable EMF Meter]: This electromagnetic radiation tester successfully tests and optimizes the compatibility of electric and magnetic field radiation to test and understand the current state of electromagnetic radiation in indoor and outdoor environments. This EMF meter cannot test RF values.

[Audible and Visual Alarm Function]: When the test result exceeds the value (0.4µT/4mg or 40V/m), the screen turns red, the indicator flashes, and the buzzer sounds an alarm. (Caution: 2-3.99mG/0.2-0.39µT, Safe: 0-1.99mg/0-0.19µT).

[Built-in Electromagnetic Radiation Sensor]: The EMF tester is equipped with a built-in electromagnetic radiation sensor, which is processed by a microcontroller chip and then displays the radiation value on the LCD screen.

Based on the test results, electromagnetic radiation can be reasonably managed or effectively avoided. [Simultaneous Display]: The digital electromagnetic field radiation detector features an LCD screen with a graphical display of radiation value trends, allowing for radiation assessment and thoughtful feedback on whether current radiation levels are safe. It can detect both electric and magnetic field radiation in a single unit, with data lock and a one-touch value lock. [Wide Application]: The electromagnetic radiation detector is stylish, compact, and portable for easy one-handed operation, making it convenient for travel or field measurements. The measurement frequency range is wider, from 5Hz to 3500MHz, enabling more accurate measurements of everyday household appliances. Applications include home, office, outdoor, laboratory, industrial sites, etc.

Note:

1. Zeroing the electric/magnetic field: After powering on, simultaneously press and hold the AVG/VPP and UNIT buttons. The zeroing interface will enter after approximately 2 seconds. When the magnetic field value is flashing and is less than 0.1 µT, briefly press the Power/Data Hold button to zero the magnetic field value. Once zeroing is complete, press and hold the AVG/VPP button to exit the zeroing interface, or press and hold the Power/Data Hold button to turn off the device. 2. When the battery icon is empty, replace the battery promptly. 3. For high-voltage installations, measurements over long distances are sufficient; remember to take safety precautions. 4. Due to possible electromagnetic field interference in the environment, there may be a slight reading when the product is switched on; this is not a defect of the instrument. 5. Manual measurements may contain errors. Electromagnetic Field: The EMF Meter has a built-in speaker that indicates the signal strength and triggers an audible and visual alarm when radiation data exceeds the safe range (electric field > 40 V/m and magnetic field > 0.4 µT). The detector flashes red and automatically alerts the user with an alarm sound. It also displays "safe" and "dangerous" on the LCD screen, making it easy to understand the results. A long press on the "UNIT" button mutes the sound.

Scope of application:

Electromagnetic radiation monitoring: Home, office, outdoors, industrial sites.

Electromagnetic radiation detection: Detection of electromagnetic radiation from mobile phones, computers, televisions, refrigerators, and high-voltage power lines.

Radiation protection product inspection: Inspection of the effectiveness of radiation protective clothing, radiation shielding films, and other protective products.
