Digital Thermometer Vs Infrared Thermometer

Thermometer: A device used to find out the temperature of any gaseous, liquid or solid matter or of a chemical reaction. It is very important to measure the temperature for a wide range of actions, including industry, scientific research, and health care actions. In health care, thermometers are used to measure the temperature of humans. They include the following types:

  • Basal thermometers
  • Oral thermometers
  • Multi-purpose thermometers
  • Eardrum thermometers.
  • Rectal thermometers

Digital thermometers: These thermometers are found with digital displays that allow easy reading of the beepers to signal temperatures when it is time to withdraw the thermometer, and flexible tubes to resist the breaking of the device.

Ear thermometers: Ear or more precisely eardrum thermometers measure temperature by reading infra-red radiations occurying from eardrum tissue.

They have three key advantages:

  1. measure temperature without coming in contact with the body;
  2. give a close estimate of the temperature of the brain (because of their proximity to the brain); and
  3. provides a readout in two or three seconds.

Basal thermometers: Basal thermometers measure small temperature changes in women to indicate whether ovulation has taken place.

Infrared Thermometers: On its most basic design an infrared thermometer consists of a lens to focus the infrared (IR) energy on top of a detector, which converts the energy to an electrical signal that is being displayed in units of temperature after being compensated for ambient temperature variation.0

Infrared Thermometer Vs Digital Thermometer

Instruments such as the IR Thermometer and the Digital Thermometer have its own advantages and disadvantages. While one is ideal for one thing and not suitable for the other. That’s why we are going to compare their importance so that you can easily choose which one of them suites our needs.

Mode of Using Thermometer

In this section, we are going to discuss the mode of using the two kinds of devices.

  • IR Thermometer

Infrared Thermometers measure the temperature from a distance as they have the ability to absorb the radiation emitting from the object’s body. They also have a laser, which releases a beam of laser and one can point it towards the specified location. It is very much specific.

  • Digital Thermometer

Digital Thermometers are known as Contact Thermometers. As its name suggests, you would have to bring the device into contact with the item or person to get the reading.

One can use this type of instruments in following three ways:

  1. Orally inserting it inside the mouth of the person
  2. Putting the probe inside the bottom part (Rectal)
  3. Placing the equipment in under arm (Axillary)

Accuracy

We would now talk about the accuracy of both the devices.

  • IR Thermometer

The IR one is a very comfortable device, consistent and very precise gadgett for measuring variation in temperatures. A better result would be obtained if the distance between the instrument and the object is lesser and if the laser is pointing towards the directed spot.

A problem, however, with this one arises if the beam isn’t aimed at the right direction or the distance is too much.

Ranging from 0 to 600 Fahrenheit, the best IR Thermometer has a correct accuracy of about ±3.5 Fahrenheit.

Digital thermometer could be used in three different ways. The accuracy of each might differ from one another.

  • Digital Thermometer

Rectal checking is far more reliable and accurate than any of them. It detects your actual core temperature as it is inserted inside your body. The least accurate method is by placing it under the arm because it is not in touch with the core parts of the body.

Oral insertion should be done in the midsection. But it is not more precise than the rectal one, as the core temperature slightly has a different temperature from an organism.

Applications

Here we are going to talk about the ways in which both of the devices can be used.

  • Digital Thermometer

As the digital thermometer can convey out readings in decimal places, it’s an excellent device to be used in fluid mediums. For example, with this device, you can see if the temperature is totally correct for a baby to bathe in or not.

  • IR Thermometer

This mostly focuses on industrial purposes such as testing to find out whether or not there are any hot spots in the cooling panel, or if the duct has any leakages or not.

It can also be used in agricultural fields and food safety purposes such as to check to see if the surrounding temperature is most desirable for the growth of vegetables. It helps the farmers to maximize their profit with least amount of stress.

Safety

Let’s talk about if the devices are safe to use or not.

  • Digital Thermometer

The very interesting fact is the thing to see how same among those who share a thermometer are being affected by the same disease. This often happens when the probe isn’t rightly maintained or cleaned after being used. Pathogens could easily move from one body to another and affect the person.

So, you have to be sure that the equipment is sanitized with antibacterial dozes each time after use

  • IR Thermometer

Since it has infrared radiation and laser involved here, it can cause severe irritation in eyes and skin. If a powerful laser is used there is a possibility of complete blindness of the person if the light beam hits the eye balls.
