RF meters, or radio frequency meters, are devices used to measure the strength of radio frequency (RF) signals in a given area. They are commonly used in various fields, including telecommunications, broadcasting, and environmental monitoring. RF meters help ensure that RF emissions are within safe limits and can assist in identifying sources of interference in communication systems. These meters typically display measurements in units such as volts per meter (V/m) or milliwatts per square centimeter (mW/cm²). Users can find RF meters in different forms, including handheld devices and stationary units. They are essential tools for professionals working with telecommunications, broadcasting, and wireless technology.
