Which is better: Digital or glass thermometers?
Digital thermometers are preferred over glass thermometers because they are more accurate, they are faster and easier to use, and they are safer (for example, if the child bites down on the thermometer). They are also inexpensive and can be used to take temperatures in the rectum, armpit, and mouth.
MYTH: Glass thermometers are unsafe because they contain mercury.
Modern-day glass thermometers do not contain mercury and are environmentally friendly. But these thermometers can still break and harm your child if they are not handled carefully.
The Canadian Pediatric Society does not recommend mercury thermometers because of their potential to cause mercury poisoning.13 If you have an old mercury thermometer at home, bring it to your city’s hazardous waste collection facility for disposal.
