Tuwei EMF Meter, 2 in 1 Electromagnetic Field Radiation Detector, High Accuracy Handheld EMF Detector, Great Tester for Home EMF Inspections, Office, Outdoor and Ghost Hunting (Black)

Work Frequency: Specially designed to operate in the natural DC range of 0‑3Hz (sub extremely low frequency itself), including the frequencies of humans and the earth itself.
Easy Operation: The operation is simple and convenient. Press the button to activate it. It needs to press and hold the button to monitor the reading.
High Quality Material: High quality ABS material is selected, which is impact resistant, fall resistant, wear resistant, not easy to damage, and can be used for a long time.
Multi Detect Range: It can measure the electromagnetic field in both the extremely low frequency (ELF) range and the extremely low frequency (VLF) range.
Detect Frequancy: The detected frequency is 50 / 60Hz (50‑1000hz‑elf) (1000‑20000hz‑vlf), and the accuracy is 5%, which is very practical.
