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/4m or 40V/m), the screen turns red, the indicator flashes, and the buzzer sounds an alarm. (Careful: 2-3.99mG/0.2-0.39µT, Safe: 0-1.99mg/0-0.19µT). [Integrated Electromagnetic Radiation Sensor]: The EMF tester is equipped with an integrated sensor for electromagnetic radiation, which is processed by a microcontroller chip and then displays the radiation value on the LCD. Based on the test results, electromagnetic radiation can be reasonably managed or effectively avoided. [Simultaneous Display]: The digital electromagnetic field radiation detector includes an LCD screen with a graphical display of radiation value trends, allowing for thoughtful radiation assessment and recall of current radiation levels as safe. It can detect both electric and magnetic field radiation in a single machine, with data lock and a single touch to lock the value.
• [Wide Application]: The electromagnetic radiation detector is stylish, compact, and portable for easy one-handed operation, facilitating travel or field measurements. The measurement frequency range is wider, up to 5Hz-3500MHz, allowing for more accurate measurements of everyday household appliances. Applications include home, office, outdoor, laboratory, industrial sites, etc.

Note:

1. Resetting the electric/magnetic field: After powering on, simultaneously press and hold the AVG/VPP and UNIT buttons, then enter the reset interface after approximately 2 seconds. When the magnetic field value is flashing and is less than 0.1 µT, briefly press the Power/DataHold button to reset the magnetic field value; once the reset is complete, press and hold the AVG/VPP button to exit the reset interface, or press and hold the Power/DataHold 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 pay attention to safety. 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 levels exceed the safety range (electric field > 40V / magnetic field > 0.4µT). 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 easier to understand the results. A long press on the "UNIT" button deactivates the sound.

Scope of application:

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

Electromagnetic radiation detection: Mobile phone, computer, television, refrigerator, high-voltage power line radiation detection.

Inspection of radiation protection products: Inspection of the effect of radiation protection clothing, radiation protection films and other protection products.
