Digital Stick Thermometers-

 A digital stick thermometer is the most widely sold and cheapest type. Look for one with an LCD that is easy to read and a start button that is easy to press. Most thermometers have an audible beep indicating that the reading is complete. This means that you won’t have to check your watch every few seconds. Digital thermometers use batteries to function.

Shopping Tips

Here is what to consider before you buy.

  • Response Time – A reading from a digital thermometer may require up to 60-80 seconds, based on the model. Infrared thermometer readings take just 1 to 3 seconds, but may not be more accurate than a cheap digital stick thermometer.
  • Safety– Some models come with protective cover cases and other accessories that may pose as a choking hazard for kids. If the model that you choose to buy includes small parts, make sure you keep them out of the hands of unsupervised children.
  • Extras– If you are purchasing an inexpensive digital stick thermometer, consider buying two. Use one to take oral temperatures and the other to take rectal temperatures. That way, you will not have to worry about keeping disposable thermometer covers on hand. Label each one of them with a permanent marker based on its particular use.
