What To Look For In An Infrared Thermometer
Engineered to operate on the principle of blackbody radiation, infrared thermometers work by gauging the temperature of any object with a temperature above zero. It goes without saying that objects of a higher temperature put out more radiating heat, which in turn makes the measuring process a lot easier.
At the same time, infrared thermometers also measure the gradient in radiation between objects, which makes their application very broad and practical. Over the next few minutes, we will try to find out as much as we possibly can about what constitutes a decent infrared thermometer and what characteristics to look for when buying one.
Application – For the most part, people use infrared thermometers for checking door and window frames for leakages, not just in construction tasks but also when renovating. Not just that but they can also be used for determining the temperature of freezers and refrigerators, which is precisely what many people use them for. It is also common for people to employ infrared thermometers for identifying potential insulation problems at home or in any storage space. These, of course, are just the most common applications for infrared thermometers but given their versatility, they can be used for so much more.
Types Of Infrared Thermometers
Spot Infrared Thermometers – These types of infrared thermometers are engineered to display the temperature on a particular spot on a surface. This makes them perfect for electric circuits that are prone to overheating throughout their entirety. They can also be used in other projects where overheating can be localized and difficult to gauge using regular instruments. Bear in mind that with these devices, you need to calibrate the thermometer to detect the emissivity levels.
Infrared Scanning Systems – These devices are a bit more complex as far as their construction goes and are commonly used in manufacturing tasks. It is common for these types of systems to be built into the assembly arrangement for larger manufacturing macro-systems. We should point out that they are best employed when scanning larger areas that involve conveyors and the like, mainly when multiple objects are involved that need to be measured en masse.
Infrared Thermal Imaging Cameras – These are more peculiar in their usage yet highly advanced performance-wise. Those who employ these types of thermometers do so as part of a complex monitoring system that requires the measurement of various points throughout an arrangement at any given time. To be more precise, many such systems operate in an automated arrangement, the type that will sometimes be required to create two-dimensional images (thermograms) either for technical or security reasons.
Features To Consider
Emissivity – This is the first thing you should consider when buying an infrared thermometer. The emissivity of an object represents how well it absorbs or emits infrared energy that can then be picked up by the thermometer’s sensors. It should be said that these values range from 0.0 to 1.0 and everything in between. In this regard, objects with an emissive value of 1.0 are referred to as ‘perfect’ emitters due to the fact that they radiate the maximum amount of energy they can.
Accuracy – Along with emissivity, a decent infrared thermometer must also perform its readings not just quickly but accurately as well. While on the subject, we should point out that experts consider adjustable emissivity to be a staple of a high-quality infrared thermometer. Many consider that the measurements should always be performed within a 1% margin of error with professional infrared thermometers and around 2% for low-end models.
Range – The temperature range of an infrared thermometer must also be considered prior to purchase as it determines just how effective the device will be when performing certain tasks. At this point, you should consider whether you need the thermometer to perform household tasks or if you need it in a more professional capacity. For regular usage, you need an infrared thermometer with a temperature range of -59 to 1022 degrees Fahrenheit but you can also opt for a more advanced model if you have the budget for it.
DS Ratio – Another thing you want to pay close attention to is the DS ratio. This determines the accuracy of the thermometer in terms of distance-to-spot; to be more exact, it determines the size of the area that you can measure in relation to distance. To put it bluntly, if an object has a DS ratio of 10:1 and measures around five inches in size, then you can expect the thermometer to perform its measurements accurately at a distance of around fifty inches or so.
Warranty – Last but not least, you should keep an eye out for a thermometer with a reasonably long warranty. We say this because infrared thermometers aren’t exactly cheap and you need the certainty that you will get the most out of such a device in the long run. Needless to say, reputable manufacturers offer anywhere between 4 to 10 years for their high-end models whereas low-end thermometers can be expected to have a warranty of at least six months.
