What Is an EMF Meter Used For?
An EMF meter is used to measure electromagnetic fields produced by electrical and electronic devices. It helps users:
- Identify sources of electromagnetic fields
- Measure EMF exposure levels
- Perform electrical safety checks
- Monitor industrial and residential environments
The Tenmars TM-191A EMF meter is optimized for ELF magnetic field measurement.
How Does an EMF Detector Work?
An emf detector works by sensing magnetic field strength produced by alternating current (AC) electrical sources. The sensor converts the detected magnetic field into a measurable electrical signal, which is digitally processed and displayed in real time.
This allows accurate detection of low-frequency EMF levels without complex setup.
