Digital Clinical thermometers are instruments that sense temperature and have a digital display and permanent probes. They are portable. They can display temperatures in Fahrenheit, Centigrade or Celsius. They can also display the range and scale. They can display one or more of these units, such as dual scale thermometers. The range displays the lowest and the highest values that can be detected by the thermometer. The scale displays the smallest in degrees that can be shown. It is also considered the resolution of a thermometer or any digital instrument.www.rightbestmedic.com
