LED Electric Magnetic Field Detector Ghost Hunting Paranormal Equipment Tester black

Operates on a single battery, and reports measurements in five milli Gauss ranges.Measure wide spectrum of Electric magnetic field from 50 Hz up to 20,000 Hz, and it can register a cell phone that is within 2 feet.Measure Electric magnetic field level protect from potentially harmful long term overexposure to meters.The Electric magnetic field Range for Ghost Hunting helps measure the electromagnetic fields to identify appliances that produce high-level emissions.Fine workmanship and good performance.Description:Item type: toolMaterial: ABSColor: Black, white (optional)Size: approx. 143*52*25mmAccuracy: +/- 5%Detection Range: 0 to 20+ milli GaussDetection Frequency: 30 - 20,000 HzBattery: 1 x 9V batteriesPackage includes:1 x Electric Magnetic Field DetectorNotes:The Five Scales: The 1st Light detects a Normal Electric magnetic field field, what is always around us. The range is between 0 to 1.5 mG. The 2nd Light (GREEN) detects a Low Level Electric magnetic field, which range is between 1.5 to 2.5 mG. The 3rd Light (YELLOW) detects a Mid Level in the range between 2.5 to 10 mG. The 4th Light (ORANGE) detects a High Level field in the range between 10 to 20 mG. The 5th Light (RED) detects an Extremely High Range of 20+ mG.  1-2cm error might exist due to manual measurements, please kindly understand. The colors deviation might differ due to different monitor settings.
