A: EMF meters measure three key factors: electric field (EF), magnetic field (MF) and ambient temperature. This ensures a comprehensive analysis of your environment, whether for radiation monitoring or temperature tracking Q: How does the sound and light alarm system work? A: The alarm system is activated when the electric field exceeds 40V/m or the magnetic field exceeds 0.4ΞΌT/4mG. The screen flashes red and the buzzer sounds a warning Q: How long can the battery be used and how do you charge it? A: The built-in 3.7V/400mAh battery can be used for up to 100 hours when fully charged. It is charged via a Type-C/USB port and takes about 4 hours to fully charge Q: Is this EMF meter suitable for health-conscious people? A: Of course. This EMF meter is a prevention tool for monitoring radiation levels in environments with electronic devices. It is especially useful for pregnant women, children, the elderly and anyone who is concerned about long-term exposure to electromagnetic radiation LED large screen Function switching Autonomous settings Data retention Highly sensitive sensor The large, clear LED digital display ensures easy and intuitive readings in all lighting conditions, making it ideal for home and professional use. Equipped with a highly sensitive sensor, the accuracy ensures that the detection error is less than 1%, thus providing reliable results Multifunctional application From checking household appliances such as TVs, computers and microwaves to monitoring electromagnetic radiation in industrial environments, this EMF meter is versatile and can be used for a variety of purposes. It is also widely used in paranormal investigations such as ghost hunting. It is the perfect tool for health-conscious individuals, pregnant women, children, office workers and seniors who are afraid of radiation exposure Review: Very sensitive - This detects every slight change. It is very sensitive. The dual display is useful. It is good quality and easy to use. It does detect some EF in areas where spooks have been seen, and there is no electrical wiring there. So this confirms the sightings. It detects the EF and MF around my devices and shows why it feels weird to stand close to them when they're in operation - some things have a high field. This device display turns red when the levels detected are high and it bleeps. It bleeps faster as the levels get higher. It is easy to silence the machine so that it doesn't bleep. It also shows temperature and humidity. Such a good price. Review: Readings of same item fluctuate - This could be human error guys but when compared to emf reader my friend borrowed from work, it old but a trusted brand. The trusted brand gave us the same reading each time where as this sometimes varies. We have to turn it off and start from scratch and not just reset it or get a continuous reading each time. In all honesty it’s been sat in the box since. ## Features - Versatile and Accurate: Discover the LCD EMF meter, designed for precise measurement of electric and magnetic field strengths across a broad spectrum of 20-3500MHz.
