Infrared thermometers are used in various industries and working environments to check the temperature of objects from a distance. Apart from the industrial use, infrared thermometers can be used to check the temperatures of food, meat, electrical equipment, automotive or another surface without having to get close to them at all. This indicates that you don’t need to touch what you are checking at all since it will be done in from a distance.

The distance of measurement depends on the type of infrared thermometer you are using as they vary when covering distances. The uniqueness of the infrared thermometer compared to the ordinary thermometer is the versatility of being used in areas where the ordinary thermometers cannot be used.

In this article, we will be looking at the best-infrared thermometer available in the market that will suit your various needs.

The Best Infrared (IR) Thermometer Buying Guide

IR Thermometer

If you want to make the right investment in an IR thermometer, there are some important factors to consider. Everyone wants an IR thermometer that will meet their needs, ranging from medical, manufacturing, automotive, food, and general application.

We will be highlighting the things to  consider in order to get the best out of an infrared thermometer:

Things To Consider When Choosing A Digital Infrared Thermometer

Temperature Range

Temperature range plays a vital role and it is a feature to look out for when buying an IR thermometer.  If what you need an infrared thermometer for is to check the temperature around the house, then you can get one with a range of -58° to 1022° Fahrenheit (-50° to 550° Celsius). In cases of more advanced use, a professional thermometer with a higher temperature range above 1487° Fahrenheit (800° Celsius) is most ideal.

Accuracy And Speed

An Infrared thermometer is considered best when it has the ability to deliver accurate and precise temperature reading within the shortest time. Accuracy has a lot to play in ensuring that you don’t make any mistake when measuring the temperature.

Note that more advanced infrared thermometers, deliver more readings with its adjustable emissivity and higher quality infrared sensors.

Looking at the functions of thermometers, the professional model of infrared thermometers provides temperature readings that are ±1% accurate, while less expensive infrared thermometers are accurate to within ±2%.

Emissivity

Emissivity is the level of reflectiveness of surfaces. We should know that every material carries emissivity and to obtain the actual temperature of materials you would need an IR thermometer that can be tuned to the correct emissivity.

If you are a professional in temperature testing, then you should get an infrared thermometer that features adjustable emissivity. For most high-quality infrared thermometers, you will get emissivity adjustment between 0.10 – 1.00 adjustments. To get the specifications or best emissivity options, then you should check the brand information to see what it offers.

Most infrared thermometers are generally designed with an emissivity locked at 0.95, which is ideal for getting the temperature reading of solid surfaces like walls, metals, and pipes. The downside of this kind of infrared thermometer is that it would be impossible for you to scan other materials like glass, liquids, and oily surfaces without adjusting the emissivity first.

Distance To Spot Ratio+

IR Thermometer

The circle of the measurement zone, which is the distance to spot ratio, is an indication of the area from which you will get the temperature reading. Your distance away from the spot determines the wideness of the object that will be read by the infrared thermometer.

Most of the infrared thermometers you will find in the market will have a distance to spot ratio around 12:1, that is a distance of twelve inches and a measurement zone (spot) of one inch. It means that when you increase your distance four times, the distance will become 48 inches and the measurement spot will be 4 inches.

Note that the most accurate temperature readings are derived from a closer distance to spot ratio.

Warranty

Always check to see how much warranty your manufacturer is offering on the product you want to buy. This is easy to overlook but if you need assurance that you are purchasing the best-rated IR thermometer then the warranty is a good indication of the quality product you are getting.

Budget

Considering the many options of infrared thermometers to pick from, your decision might be influenced by your budget, depending on how much money you have or you are willing to spend on such devices.

If you don’t need to use it often, but only at home when the need arises, then you might as well settle for a lower price range. You need not spend extra if your need is for a basic infrared thermometer that has fixed emissivity, limited temperature ranges, and less accuracy.

Alternatively, if what you need is an infrared thermometer that is purpose-built, with specific more features that serve your professional or industrial needs, then you have all the reason to invest in a higher quality infrared option that will give you more bang for the money. A weak budget should not stop or scare you away from getting an infrared thermometer, all you need to do is to properly read and evaluate each of the reviewed infrared thermometer and find what fits your need.


CONCLUSION

Your conclusion or final decision about the best infrared thermometer should not be a difficult decision to take now that all the information you need to know has been made available. All you need to do is to carefully check your need and make your choice. We hope that the review and the buyers’ guide would have properly informed you about some of the top infrared thermometers out there on the market. Although some of them can be a little tricky to operate, but you don’t need to be a rocket scientist to get it working, all you need is a little time and patience to work it once or twice and you start getting the hang of it. Hope you get to make a good choice of getting yourself an infrared thermometer.
