How To Use Safety First Ear Thermometer?

Gone are the days when you take your body temperature using conventional glass thermometers with hazardous mercury content. With today’s technology, everything is becoming digitized. There is no need to wait for a couple of minutes to detect body temperature.

With the safety first ear thermometer, you can measure the temperature of energy radiating from the eardrum. So if you are wondering how to use safety first ear thermometer to get the right measurements, read through this quick guide to learn everything you need to know about the device.

What Is It and How Does It Work?

Before we dive right into the proper steps in using the digital ear thermometer, are you not curious about how it works? It is necessary that you know the work of a device in order to use it to its full potential.

A safety-first digital thermometer uses the ear or tympanic method that is recommended for children older than 2 years old. The eardrum is deemed an accurate point to measure body temperature.

The only problem with measuring body heat through the ears is that it’s too fragile. A touch to the drums can cause serious hearing problems. With that, the detection of temperature using the eardrums delivers a remote sensing problem.

Working Principle

So how does it work? Through infrared radiation. This detection technique is an efficient way to sense body temperature through a person’s eardrums. The infrared energy coming from your head passing through your eardrums is sensed by the ear thermometer.

Though easy and quick to use, they can produce readings that are incorrect. You can follow safety first ear thermometer instructions by the manufacturer, but it is best that you learn about some tips from first-hand users.

Without further ado, here is a step-by-step process on how to use the ear thermometer as well as side tips for maintaining the cleanliness of the tips.

How to Use Safety First Ear Thermometer?

Since there are many kinds of safety first ear thermometers available in the market today, we made this guideline easy to understand and as general as possible.

  1. Using clean and properly sanitized hands, take the thermometer out of its box or holder.
  2. Test the device to see if it is working by turning it on and then off. Make sure that you are using the right safety first ear thermometer battery for accurate readings and clear LCD display.
  3. Remove the cap that covers the tip of the thermometer and place it in a secure and clean area to prevent it from getting contaminated.
  4. Put a new, disposable cover over the thermometer’s tip.
  5. Checking the temperature of a child and an adult is different. For toddlers, gently pull the child’s ear straight back. On the other hand, gently pull the ear slightly upwards and then back for adults.
  6. Slide the covered tip into the ear opening. Make sure NOT to force the tip inside. The tip of the thermometer should not touch the eardrum. (Safety tip: Most safety first quick read ear thermometers will have markers that will tell you when to stop pushing the device inside.)
  7. Press the button to turn on the thermometer. Hold it until you hear a beeping sound or follow the safety first ear thermometer manual to know how to operate the device.
  8. Most ear thermometers will beep once a reading is done. If so, you can check the window or the LCD display for the measured body temperature. Turn off the device after use.
  9. Remove and properly discard the disposable tip cover for the next users.
  10. Sanitize the tip of the thermometer using cotton buds and rubbing alcohol before placing it back in its box or holder.

Safety Tips

While these digital ear thermometers are created to be simple and straightforward, they are still mechanical devices that should be properly stored and used with care.

Clean Your Ear

Make sure the ears are clean and free of wax. One of the reasons why ear thermometers provide wrong and inaccurate readings is because of the wax that blocks the infrared energy coming from the eardrums.


Do not use an ear thermometer on the following occasions:

  • When a person has a sore ear
  • When there is an ear infection or Acute Otitis Media
  • When there is a fresh wound near the ear opening
  • When a person just had ear surgery

For safety —never use the same thermometer for rectal and oral methods.


Now that you know how to use safety first ear thermometer make sure to spread the word to your family members. You may not be around all the time, and this knowledge will be useful for whenever they are going to use the device themselves.

In addition to that, you can maintain the cleanliness and accuracy of the device if everyone in the household knows the guidelines.
