[DETAIL] Description: Color: Black 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 Features: -Easy-to-read multi-segment LED display. -The EMF Meter Range for Ghost Hunting helps measure the electromagnetic fields to identify appliances that produce high-level emissions, allowing users to make informed decisions about limiting exposure. -The detectors have been associated with locations, where unexplained phenomena have been reported like alleged haunting. -The Ghost Hunting Detector operates on a single battery, and reports EMF measurements in five milliGauss ranges. -Measure wide spectrum of EMFs from 50 Hz up to 20,000 Hz, and it can register a cell phone that is within 2 feet. -Measure EMF level protect from potentially harmful long term overexposure to EMFs. -Convenient push-on/push-off operation; Portable, easy to use, rugged, reliable, super responsive with easy to read LED light scale in dark and sunshine. 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 Notes: 1. Manual measuring, please allow 1 ~ 3mm error,thank you. 2. Due to the difference between different monitors, the picture may not reflect the actual color of the item.
