Advantages And Drawbacks Of Non-Contact Thermometer


Thermometers have played an important role in the medical field as well as in other fields. However, the first thing that comes to your mind when you imagine any thermometer that,  a sick individual holding a thermometer in his or her mouth. Thermometers help people measure their body temperature and indicate if one has normal body temperature. Whether he has a higher temperature like in case of fever or has low body temperature that is when an individual is hypothermic. Non contact thermometers were used in industry for many years. However, because of the pandemic, they have been widely used because other thermometers, such as oral, armpit, and ear thermometers, could not be used during the pandemic.

Temporal or forehead thermometers 

This thermometer is a no contact thermometer which measures temporal artery temperature using an infrared sensor. The temporal artery is the carotid artery part. Some are even known as infrared non-contact thermometers.

The Thermometer non contact does not need physical contact and is becoming increasingly popular. They are commonly used at airports and malls. In addition, they can also be seen at stores and stadiums. The forehead temperature is approximately 1oF lower than the temperature measured by an oral thermometer.

Some of their advantages are as follows:

  • Thermometers that provide temporal readings produce results quickly. They provide results in a matter of seconds, and are highly manageable. They can be used on individuals such as adults and children and also on infants.
  • According to certain researchers, temporal readings are accurate, and their accuracy may be compared to rectal thermometers that are used for children.
  • No-contact thermometers produce better results than ear or armpit thermometers. But these findings are still debatable and are subject of debate in numerous other studies.

Thermometer non contact has some drawbacks, despite their many advantages. These are as follows:

  • Forehead non-contact thermometers, including other non-contact thermometers, must be precisely positioned. Based on the manufacturer’s guidelines, forehead non-contact thermometers must be pointed precisely at an individual’s forehead to provide a correct reading.
  • External factors such as direct rays of sunlight and indoor heating. In addition, winds may also have an impact on the results.
  • Wearing specific clothes, like heavy coats and hats, may cause the results to be skewed.

Non-contact thermometer non-contact comes with a removal cap to keep it clean while storing. This cap must be removed before use. Above all, always read the instructions that come with the device, as a forehead thermometer differs depending on the manufacturer.
