ELECTROMAGNETIC FIELD GAUSS METER EMF K2 Magnetic Field Tester EMF Rating Tester Portable 5 LED Gauss Meter The EMF measurement range helps measure magnetic field in high-quality testing equipment, ensuring that users are given the decision to limit their range Ghost hunting detector acting on one of the electrodes (9 V) Portable, easy to use, functional, functional, super responsive Ear: 12x8 cm/4.7x3 inches Field Tester EMF Tester Portable Gauss Meter with 5 LEDs. The range of the electromagnetic field meter helps measure the field to identify high-generating devices, allowing users to make decisions about reducing exposure. Easy to read multi-segment LED display, used for paranormal phenomena research and for general electromagnetic field detection. Hunting operates on a single battery (9 V), EMF levels are measured to prevent potentially harmful long-term excessive exposure to EMF. Portable, easy to use, sturdy, reliable, super responsive. Cutting in metal in a sustainable way, a solid frame and an alternative model of opening made of metal. 1. Multiple detection range: It can measure electromagnetic field in both very low frequency (ELF) and very low frequency (VLF) ranges. 2. Operating frequency: Specially designed to operate in the natural DC range of 0-3 Hz (very low frequency alone), including the frequency of people and the earth itself. 3. Easy operation: The operation is simple and convenient. Press the button to activate it. To monitor the reading, press and hold the button. 4. Detection Frequency: The detected frequency is 50/60 Hz (50‑1000hz‑elf) (1000‑20000hz‑vlf), and the accuracy is 5%, which is very practical. 5. High-quality material: High-quality ABS material is selected, which is resistant to impact, fall, wear-resistant, not easy to damage, and can be used for a long time. - Inner mesh panties Item Type: EMF Meter; Material: ABS Product Length: Approx. 14,3 cm / 5,6 inch Weight: Approx. 131g / 4,6 oz Battery: 6F22 9V Lithium battery, 800mAh (with built-in battery provided) List of packages: 1 x EMF Meter 1 x English Manual 1 x batteries Use Step 1:Start the tester, press and hold the tester switch with your thumb, all the LEDs will flash in sequence, the meter will start the self-test program, and the first green LED will always be on. Step 2:Place the device near the electromagnetic field source, the LEDs will indicate the electromagnetic field range for this level, and the LEDs will flash. Step 3: Moving or rotating the device from side to side can change the reading, the highest reading is the most accurate.
