UPGRADED K2-B Deluxe EMF Meter with Built-In Constant On-Off Switch and Low Volume Sound – Includes Instructions. This model delivers the same effectiveness and performance as the original K2 meter. Widely used in numerous investigations with reliable results. NOTE: This is a KII meter that provides an audible low volume sound when EMF is detected. The sound is intentionally low to avoid interference during investigations. The low-volume alert resembles a Geiger counter and increases in intensity as each detector bar lights up. Please note the sound level is kept low to prevent disruption of evidence collection. All other specifications and operating functions are consistent with standard KII meters. Model: KII-B The KII-B enhances the popular KII design by adding a low-volume buzzer for EMF detection. This feature allows paranormal investigators to both see the illuminated LEDs and hear EMF changes simultaneously. Unlike the standard KII, this model enables users and team members to audibly detect EMF fluctuations in real time. The audible feedback can support validation of events, especially when paired with audio or video recording devices that capture the sound. Provides an effective audible alert for monitoring EMF changes from a distance. The buzzer increases in intensity with higher EMF field strength. This model is used by professional investigative teams. For those seeking a dependable EMF meter trusted in the field, this is an ideal choice. Electromagnetic fields (EMFs) are emitted by various electrical sources, including appliances, cell phones, wiring, and electronic devices. The K-II EMF meter measures these fields, helping identify sources of elevated emissions so users can make informed decisions about exposure. The device operates on a single 9V battery and displays EMF levels across five milliGauss ranges. Key Features: - Instant response to EMF fluctuations and spikes - Detects ELF range (50 to 1,000 Hz) and VLF range (1,000 to 20,000 Hz) - Simple push-on/push-off operation - Easy-to-read multi-segment LED display - Accuracy of ±5% at 50–60 Hz
