EMF detector fast response EMF meter 5 level for supernormal wave research Feature:1. Five levels: The EMF detector has five levels of detection indicators that represent different values of EMF2 radiation. Fast response: The meter has a quick response, the test results will respond quickly, immediately responding to EMF fluctuations and spikes3. Small and portable: The magnetic radiation detector is small and lightweight, convenient to carry and easy to operate4. Durable ABS Material: The detector is made of ABS engineering material, which is sturdy, durable, and reliable5. Application: this magnetic radiation detector is usually used for supernormal wave research and general EMF detection, etc. Specification:Item Type: EMF DetectorBattery: ABS Battery: 1x9V 6F22 (Not Included)Application: Used for Supernormal Wave Testing and General EMF DetectionBasic Value:Detection Range: 0-20+milliGaussDetection Frequency: 50/60Hz (ELF: 50 to 1000Hz), (VLF: 1000 to 20,000Hz)Accuracy: 5% (Typical)Package List:1 x EMF detector1 x User ManualUsage:1. Hold the EMF meter with your thumb on the switch.2. Point towards the EMF source, then press and hold the switch (the LED will have a short flash).3. The LED will indicate the EMF range at this level.4. Moving the device from side to side or rotating can change the reading, the highest reading is the most accurate.5. Move closer or farther to the EMF source to determine the normal zone as indicated by the green LED. 1) we accept Alipay, West Union, TT.
