The range of EMF meters used for ghost hunting helps to measure electromagnetic fields to identify devices that generate high radiation, enabling users to make decisions about limiting exposure.Easy-to-read multi-segment LED display. The detector is associated with the location and it is reported that the unexplained phenomenon is related to radiation.The Ghost Hunting Detector operates on a single battery and reports EMF measurements in the 5 milligauss range.Measuring a variety of EMFs from 50 Hz to 20,000 Hz, it can register mobile phones within 2 feet.EMF levels are measured to prevent potentially harmful long-term overexposure to EMF. Specifications: EMF Meter Magnetic Field Detector Ghost Hunting Paranormal Equipment Color: Black,Grey Material: ABS Accuracy: +/- 5% Size: 14.3cm x 5.2cm x 2.5cm (L*W*H) Detection Range: 0 to 20+ milliGauss Detection Frequency: 30 - 20,000 Hz Battery: 1x 9V batteries required (not included) The Five Scales: The 1st Light detects a Normal EMF field, what is always around us.The range is between 0 to 1.5 mG The 2nd Light (GREEN) detects a Low Level EMF, which range is between 1.5 to 2.5 mG. The 3rd Light (YELLOW) detects a Mid Level EMF in the range between 2.5 to 10 mG. The 4th Light (ORANGE) detects a High Level EMF field in the range between 10 to 20 mG The 5th Light (RED) detects an Extremely High EMF Range of 20+ mG Package Included: 1 x EMF Magnetic Field Detector (Battery is not included)
