An Ultrasound Watt-meter (Radiometer) are testing devices used in performing output measurement tests and performance verification on ultrasound equipment. Mostly, these multifaceted devices performs primary measurements of total-pulsed or continuous-average power (in watts) measurements. These devices are tested using either distilled and/or degassed water (never use regular tap water for performing measurement checks--will result in inaccurate readings). Lastly, technicians can store, print data, or possibly transfer it to an automated computerized maintenance management system for archival.
