Radiofrequency power meters designed to assess the power output characteristics of shortwave diathermy units, typically operated at 13.56 or 27.12 MHz. These devices are capable of measuring a continuous range of frequencies, typically from 10 to 30 MHz; the results are usually expressed in watts in a range from zero to one kilowatt. These meters are typically power measuring instruments that measure on a 50-ohm load and probes appropriate for coupling with inductive and/or capacitive diathermy units.
