I am selling a used Braun ThermoScan IRT3520 ear thermometer. It comes as shown in the photos in it own case and full instruction manual.The thermometer works but the temperature is not correct. Probably needs a good clean as according to the barcode the machine was manufactured 25 April 1992 - 34 years ago. The thermometer uses 2 CR2032 batteries and the push button is marked from constant use as shown.
