How to Use an Infrared Thermometer?

A thermometer is one important tool that needs to be available in any home. The thermometer is a convenient and easy way to measure body temperature. Besides being used at home, the infrared thermometer can be used anywhere at any time to anyone.When putting close to one’s forehead, its backlit screen will indicate the detected temperature.

These type of thermometers have several functions in your house that you can never imagine. They can be used in checking the temperature of surfaces. It is useful in the kitchen as it can detect when to use your oven for baking. For frozen food that makes probe difficult to penetrate, infrared thermometer got you sorted. Its ease for use is what makes it ideal temperature measurements.

This sounds easy to anyone, but there are basic tips you need to know before using the infrared thermometer. These tips are also important for you when choosing the thermometer. Read on and know more about the infrared thermometer, how to use it and how to know the right one to go for.

How Does The Infrared Thermometer Work?

You may wonder how an infrared thermometer detects one’s temperature with accurate degrees and at high speed. That is everyone’s curiosity. The reason it is called infrared thermometer is that it uses infrared lights that detect an object to the thermopile of the detector. Upon pointing it close to our bodies or forehead, the thermopile absorbs ultraviolet radiation turning it into electricity.

As the object absorbs more infrared energy, it gets the thermopile hotter. This electricity is later sent to the detector, thus telling the temperature of whatever is being measured. The hotter the object gets, the more electricity emitted. With this process, accuracy is guaranteed, and it is faster too.

When Should I Use an Infrared Thermometer?

An infrared thermometer is not always the right tool to measure temperature though it is much useful. One thing to note is that an infrared thermometer only measures the temperature of surfaces. Thus should not take temperatures of internal food.

That should not discourage you as there are other models with foldable probes that got you sorted in internal food temperature detection. As infrared thermometer uses a laser to determine the temperature of a surface, the air carrying moisture, dust particles or smoke is likely to interfere with the accuracy of the temperature.

Infrared thermometers do not measure the temperature of stuff behind a transparent surface or glass. The thermometer will only read the glass’ temperature and not the item’s temperature. This is the case even if you can see the red circle on the item. The same case applies to the measurement of water’s temperature. The infrared thermometer detects the temperature of the water on a surface not when inside a container or other enclosed place.

How to Use an Infrared Thermometer Correctly?

There are simple things you need to know before taking the infrared thermometer for temperature measurements. It not only measures a dot but even an area. The longer your aiming area, the bigger your area of measurement. All you need is learning the ratio distance you are aiming at to be able to get close to the target and get precise results. Remember always to preserve the lens of the thermometer from stains and keeping it clean.

Also, let your thermometer take two or more temperature measurements for accuracy. We have already known an infrared thermometer is the best for use in determining temperature. As an ideal thermometer for checking the deck oven, grills and pans’ temperature, it also checks the temperature of frozen or refrigerated item surfaces.

An infrared thermometer can also have a quick temperature check of mixed items on buffets. This is to ensure the mixture have a uniform temperature. Infrared thermometers have thumb-activated buttons while some have trigger-like buttons. They are useful in activating the projection lights of the thermometer that shows a circle on the aimed surface or area.

The highlighted area with the circle shows the distance of the temperature reading as you pull the thermometer further from the surface; its area increases. Note that, as you pull the thermometer away from the surface may affect the accuracy of the reading. Go through the manufacturer’s manual to know how far you can hold your thermometer from the surface while taking readings.

Check These Additional Guidelines to Help You in Using Your Infrared Thermometer:

  • For your infrared thermometer to last and have accuracy in your temperature reading, clean it regularly—especially the thermometer’s lens.
  • When handling it, do no look directly into the beam laser. It might cause permanent damages to your eyes.
  • Before taking any product readings, remove all barriers like plastic film and glass doors. It ensures you get accurate readings of the product as there will be no barriers between the product and the thermometer.
  • Having sudden changes in temperature detection can make it hard to get an accurate temperature.
  • Before getting the temperature of any soft food and liquid, stir it thoroughly.

Choosing The Best-Infrared Thermometer in The Market

Getting a good quality infrared thermometer is nothing hard. The trick of having a durable thermometer is how you take good care of it. There are also other aspects to focus on when selecting a good infrared thermometer. First thing before choosing your thermometer for purchase is testing it; you need to test it severally for your accuracy.

The next thing to do is checking its temperature and emissivity. The thermometer’s emissivity determines its ability to read the temperature of different materials. In this case, one out of ten thermometers allows you to adjust the amount of energy emission. The infrared thermometer’s temperature directly impacts any work you do with it.

Last but not least, go for an best infrared thermometer that has a quick data recording and reading speed. Lastly, check the thermometer’s warrant; it can break down sometimes, and it is a necessity for some thermometers to have a warranty feature.

How to Get Profuse Results With an Infrared Thermometer

An infrared thermometer gives you quick and accurate temperature readings without touching the surface or object being measured and at a distance. It is fun to work with, easy, convenient and has become a must-have in the kitchen area. Often, the infrared thermometers are used in finding electrical circuits, overheated equipment and have other wide range functions.

1. Check your measurement distance

the infrared thermometer has a specific ration of distance and speed. It tells you how far you should hold your thermometer from your target. With this, you will be able to get your readings accurately. The distance-spot ratio varies in each infrared thermometer from 1.1 to 60.1. to know about your thermometer distance spot ratio, go through the manufacturer’s manual or the label on your thermometer.

2. Bright shiny objects

Infrared thermometer guarantees you great accuracy when getting the temperature of objects. When it comes to shiny objects, getting the accuracy of their readings can be difficult. To get accurate readings of shiny objects or surfaces, apply flat paint or place a non-reflexive tape over the object. This will help you get a target to take your readings.

3. The laser should not lead you astray.

Some infrared thermometers, especially the handheld, have laser pointers that display the area measurement centre. Keep in mind that the laser is a pointer and not what is used to get the authentic temperature reading.

4. Temperature shock

When trying to get higher accuracy, let your thermometer regulate with the temperature of its surrounding for sometimes. Twenty minutes is enough for the thermometer to come to term to its surrounding temperature- whether hotter or colder than its original storage place. With non-contact infrared thermometers, you do not have to worry about leaving the thermometer for sometimes to adjust, its convenience, accuracy and speed is guaranteed, only when properly used.

To have the best temperature readings from an infrared thermometer, here are tips to remember;

  1. Dust or steam can affect the accuracy of your readings.
  2. Your thermometer lens should be free from scratches and clean always.
  • For accurate temperature reading, allow your thermometer to stay in the reading area for sometimes.
  1. Read your infrared thermometer manufacturer’s manual to know the ratio distance between your thermometer and the spot. It is not a hard thing to do a test of your thermometer temperature reading from a close distance and a far distance to know their accuracy.
  2. Pay attention to low emissivity or shiny objects.

What are Some of The Uses of Infrared Thermometers in Industries;

  • In cases of electrical circuits with high powers, they find faults
  • .
  • In electrical switch gears, they identify their problems.
  • It is getting the temperature reading of fuses that are near or far from their current rated capacity.
  • In large motors and rotating equipment, it measures their bearing temperatures.

In summary, when using an infrared thermometer, you should note that it does not read the temperature of solid food items like chicken or steak. This is because their internal temperature varies thus difficult to get the accurate reading. Also, as much as it is easy and fun to use an infrared thermometer, it can be tricky to get your temperature accuracy.
