An infrared thermometer is commonly used to see if a surface is hot or cold. They work by using infrared energy from an infrared source, which passes through any substance set on. Once the infrared energy has passed through, it will tell the reader if the surface is hot or cold. Infrared thermometers can be used to detect electrical circuits and overheating electronics, but there are hundreds of other uses for them as well. However, some “gotchas” with infrared thermometers will cause inaccurate readings or produce wrongfully influenced by the source of energy.
The first way that infrared thermometers can come out incorrectly is if they are set up incorrectly. There are specific ways to measure temperature with infrared thermometers that involve setting them up with specific temperatures and time intervals. You should only use a different type of thermometer for measurements then you are using for your other measurements. This can prevent you from accidentally setting the thermometer wrong, causing it to get unrelated measurements to the temperatures it is meant to read.
Another way an InstrumentChoice infrared thermometer can come out incorrect is if it has a surface where it is not supposed to. If the surface is slick or has a unique contour that causes the reading of its temperature readings to be different than it should be, then it is not an appropriate surface to use. For instance, if the surface has an unusual curvature, then the readings from the device will be inaccurate. In addition, some surfaces have properties that allow them to be slippery, such as plastic and metal. You should also avoid places with excessive grease, as this can also affect the performance of your infrared thermometer.
One other way that an infrared thermometer can come out incorrect is if it takes your measurements at the right temperature. Temperature measurements that take place at room temperature are more appropriate than those that take place in a freezer or other frigid environment. When measuring temperatures in these environments, you are more likely to come up with an incorrect result. This is because body heat is not going to change very much with a reduction in temperature. A person feels cold in the first place because their body is emitting heat to move against gravity and stay within the same space.
If you are measuring temperatures in a lab setting, you should try to ensure that the infrared thermometer you are using has a minimum and maximum reading. The lowest reading will be the closest thing to a perfect measurement, while the maximum is going to be more accurate. This is because there are factors such as surface material and the ambient temperature that go into the calculation of the distance-to-spot ratio. Therefore, an excellent infrared thermometer has a decent range and has decent maximum and minimum temperature readings.
Some factors go into determining the level of accuracy for infrared thermometers. Some of these factors are the distance between the sensor and the surface that it is set to measure temperatures on and the surface density of that particular material. You have to realize that the only thing that will cause temperature readings to be accurate is human error. The random variations that come from the human body add an amount to the readings that you get. Therefore, the quality of your readings will have a great deal to do with how you react to a cold or hot environment.
