Iriisy Electromagnetic Radiation Detector, Gauss Meter EMF electromagnetic field K2 radiation detector, portable EMF magnetic field monitor, 5 LED Gauss Meter (black)

["【5 LED Indicators】 The LED light design allows you to easily read the data in darkness and sunlight. 5 LED indicators with special functions represent different radiation values.","【50Hz to 20,000Hz】 Measure a variety of electromagnetic fields from 50 Hz to 20,000 Hz, can record cell phones within less than 2 feet.","Portable, easy to use, durable, reliable, and responsive.","Works with a battery (not included) and reports EMF measurements in ranges of five milli-Gauss.","The range of the EMF meter for ghost hunting helps measure electromagnetic fields to identify devices that generate high radiation, allowing users to make decisions to limit exposure. EMF levels are measured to avoid potentially harmful long-term overexposure to EMFs."]
