Specifications: 9V, 5 milliGauss, 50 to, 1000 Hz, 60Hz, 1 K, 2 black

Features: are the same as other KII detectors. KII-B model: The KII-B adds a low-frequency buzzing sound to the popular KII electromagnetic field detector, which emits a warning sound when an electromagnetic field is detected. This sound feature allows paranormal investigators to simultaneously see the LED indicator light up and hear the warning sound of electromagnetic field detection. Unlike the standard KII, the KII-B allows investigators and others to hear warning sounds for electromagnetic field detection. Unlike the standard KII, the KII-B allows researchers and others to directly hear changes in electromagnetic fields. This audio technology also helps validate your experience, as some people typically use tape recorders or digital video recorders to record changes in electromagnetic fields. This is an excellent audible alarm feature used to monitor electromagnetic field changes in remote areas. As the intensity of the electromagnetic field increases, so will the buzzing sound. Professionals, including TAPS (the supernatural investigation team in the science fiction TV series \"Ghostbusters\"), use these devices. If you want professionals to use high-quality electromagnetic field detectors, then this is what you need! Electromagnetic fields are generated by various types of electronic devices. Electromagnetic fields are everywhere, originating from household appliances, mobile phones, wiring, and even the human body. The K-II electromagnetic field strength meter can measure electromagnetic fields, identify devices with high radiation, help users make informed choices, and reduce exposure to electromagnetic fields. Fluctuations in electromagnetic fields are also related to the occurrence of certain unknown phenomena, including so-called \"ghost sightings.\" The K-II electromagnetic field strength meter can measure electromagnetic fields, identify devices with high radiation, help users make informed choices, and reduce exposure to electromagnetic fields. Fluctuations in electromagnetic fields are also related to the occurrence of certain unknown phenomena, including so-called \"ghost sightings.\" The K-II is powered by a 9V battery and has a measuring range of 5 milliGauss. Can instantly react to fluctuations and peaks in electromagnetic fields. Can detect extremely low frequency range (ELF) (50 to 1000 Hz) and extremely low frequency range (VLF). Easy to use, just open/close. Equipped with an easy-to-read multi-strand LED display. At a frequency of 50-60Hz, the accuracy is 5%. Packing list: 1 K2 black model with battery included (color box)
