A radio frequency (RF) wattmeter measures and documents the electric power of a given circuit. RF wattmeters log this data in watts on an easy-to-understand display scale. Engineers use wattmeters to collect information on the electrical energy supply rates for utility frequency, audio frequency, and RF power. ValueTronics offers used and refurbished RF wattmeters and wattmeter components/elements at competitive prices. At ValueTronics, you can find wattmeters from many top manufacturers, including Bird, Boonton, and Instek.
