The Parker Thermasonic 83-03 Temperature-Adjustable Ultrasound Gel Warmer is one of the most advanced products of its kind. Unlike many Gel Warmers, which have only one temperature setting or limited temperature controls, the 83-03 can be set to any temperature between 97° and 109° F (36° to 43° C) in single degree increments. This feature provides a great degree of adjustability for individual patients. The LCD screen displays the current temperature setting, complying with JCAHO standards.
