K2 flowmeters are often used during ghost-hunting and are also used for personal safety to identify potentially harmful high EMF radiation. The K2 flowmeter is known for its reliability and quality in the investigation of paranormal phenomena. This makes the K2 EMF instrument an perfect tool for detecting mental activity and finding potentially harmful high EMF levels in a home or work environment. /////////////////////////////////////////////////////////////////////////////Type 1/////////////////////////////////////////////////////////////////////////////////// Features: Simple operation and highly sensitive. Can detect the power of electromagnetic radiation around home electronics, electric wire, industrial equipment and so on. Wide range of detectable frequency. Data hold function. Applications: For detecting environmental electromagnetic radiation: indoors, computer station room, industrial control room, electric wire, high voltage wire, monitors, etc. For detecting home electronics: cellphone, PC, TV set, copy machine, fax machine, microwaves, refrigerator and so on. NOTES: The dosimeter is for testing the electric field radiation. If the test equipment earthing shielded, the test would fail. Metal will shield the radiation, too. If the meter keeps display "0" while testing, please change a battery and test again.
