It can be used for troubleshooting problems in battery banks and power panel terminations. It can also be utilized for determining poorly insulated areas around the house. Indeed, an IR thermometer is very versatile.
Difference between a Traditional Thermometer & an Infrared Thermometer
You’d probably realize the difference between a traditional thermometer and the best non contact thermometer by now. An IR thermometer doesn’t need the user to be in close contact with an object to be able to measure its temperature. An infrared thermometer can be used in industrial and manufacturing settings were a typical thermometer cannot be used or not as effective. These include taking temperatures of objects containing hazardous materials like acids. It can also get temperature of objects in an area where access is extremely limited. It can be effective in measuring temperature of objects which are moving l, or which are extremely hot that direct contact is impossible.
How Does an Infrared Thermometer Work?
The technology that makes an IR thermometer may appear complex but its concept is really simple. Everything around us emits some amount of energy. That energy is emitted in the form of heat. Since there’s heat being emitted by an object, an IR thermometer simply detects the difference between the IR rays emitted by the object and those in the surrounding environment. The difference is the surface temperature of the object being pointed at by the thermometer’s laser. An infrared thermometer has three parts—lens, thermopile, and detector. The lens focuses on the IR radiation being emitted. The thermopile, meanwhile, is a detector that converts the IR into heat. It is also in the thermopile where the heat is converted into electricity. This in turn is sent to the detector, which translates the electrical output into a temperature reading. The said reading is then flashed on the LCD display in a matter of seconds.
Things to Consider Before Buying an Infrared Thermometer
This infrared thermometer review will also help you choose the best infrared thermometer by giving you a list of factors that you need to take into consideration.
Temperature Range: This is arguably the most important consideration in buying an infrared thermometer. You obviously want the best non contact infrared thermometer with a wide temperature range. Most infrared thermometer models can measure temperatures from a low of -50 degrees Celsius to a high of 500 degrees Celsius. In terms of Fahrenheit, infrared thermometers can read temperature within -58 to 932 degrees. But the high-end ones can measure temperatures up to 1,000 degrees Celsius. Yet this doesn’t mean that you should buy a high end thermometer that can measure temperatures of such levels. This is particularly true if you intend to use it in home applications only.
Convenience: Infrared thermometers are convenient to use. After all, you simply have to aim, pull the trigger, and the display will show the temperature reading. But for pros, a unit that would allow them to clip it to a belt bag or tool bag comes in handy especially if they need to use both their hands like when climbing a ladder.
Emissivity: This is simply defined as the ratio of energy radiated by an entity to the energy released by a black body at the same temperature. All values of emissivity range from 0.0 and 1.0. The perfect radiator or black body has an emissivity of 1.0. Most entry-level infrared thermometers have a fixed emissivity value allowing accurate and reliable temperature measurements for the vast majority of objects. But if you are to read the temperatures of shiny or transparent surfaces like polished steel, glass, and cast iron, a thermometer with a fixed emissivity value isn’t ideal. You must get one with adjustable emissivity value. But you will have to shell out more money as a thermometer with adjustable emissivity is more expensive.
Field of view: Distance to spot ratio should be a convenient one. It should suit the sort of work you want to do with it. This is the ratio of Distance and spot ratio of the object that is needed to be measured its temperature through infrared thermometer. All you need to first consider what ratio you want to deal with it. If the ratio is about 10:1 then choose 5-inch thermometer field of view. A quality infrared thermometer is capable of measuring 50 inches of an object. This can be adjusted with the distance-spot ratio of the object between 1 to 50 inches.

How to Use an Infrared Thermometer
Powering Up: Most of the best infrared thermometer units are powered by batteries. There are those which require AA batteries, which is arguably the most commonly available. Others operate on AAA or 9 volt alkaline batteries. Some are powered by rechargeable lithium ion batteries. Battery compartments are usually located in the handle of the unit.
You obviously have to put the battery into the thermometer before you switch it on. Once you have correctly installed the battery, simply turn on the unit by pressing the on/off button. The best infrared thermometer usually has an automatic shut-off feature, which turns off the unit after a certain period. Some units automatically turn off in 10 seconds; others in 15 seconds.
Choose unit of measurement: You will have to select your preferred unit of measurement. Most units have Fahrenheit as the default unit of measurement but you can easily change this. You can look at the LCD screen to check the current setting, usually in °C or °F symbols.
Measuring a temperature: You can then point the thermometer at the object. Then pull the trigger. Most of the time, the temperature reading will be displayed on the LCD screen in one second, or even less. You can even release the trigger and still have the reading displayed on the LCD.
If you are to use a single laser pointer, do note that there’s a small distance from the middle of the temperature measurement required for the unit to accurately get the reading. For dual laser pointers, the area in between the laser dots is often the spot where the device will take the measurement.
You can always refer to the instruction manual of the thermometer to know how to get the exact temperature measurement.
How Accurate are Infrared Thermometers?
Numerous studies have found infrared thermometers as accurate as traditional thermometers, particularly rectal thermometers which many health experts believe is the best method of measuring body temperature.
A recent study involving an infrared thermometer had experts at Akron Children’s Hospital in Ohio taking 450 measurements in children aged 2 years old and below. They used both forehead and rectal thermometers. There was a difference of around 0.03 degree Celsius between the IR thermometer and rectal thermometer.
Hence, it can be said that readings of both thermometers are almost the same and that IR thermometers are pretty accurate.
Most Common Misconceptions About Infrared Thermometers
1. It is the laser that measures the temperature of the object.
Actually: No, the laser pointer is simply a guide that tells you where you are pointing the thermometer. It doesn’t measure the temperature of the object that you are pointing at.
2. The infrared thermometer measures the internal temperature of an object.
Actually: This is another myth about infrared thermometers. On the contrary, an IR thermometer simply measures the temperature of an object’s surface, like the food, grill, skillet, oven, refrigerator, and swimming pool.
Frequently Asked Questions
1. Why does an IR thermometer have a different room temperature reading as a wall thermostat?
Answer: The IR thermometer measures the surface temperature of the object which you are pointing it at. The wall thermostat meanwhile displays the temperature reading of where its sensor is located, which is not always the same as the temperature that the IR thermometer is reading.
2. How do I clean an IR thermometer?
Answer: Simply wipe it clean with a soft cloth or cotton swab with alcohol. Don’t use chemicals or soap as these may damage the unit.
3. How often should I clean an IR thermometer?
