What are the best tips for IR temperature measurement?
The process of measuring the temperature of the infrared (IR) relies on the determination of the amount of invisible light issued by objects in the form of infrared radiation. In order to get the most accurate IR temperature measurement, there are several general tips that can be monitored. When using non -contact IR thermometer, it is important for both the lens and an object that is measured as clean, dry and without any obstacles. It may also be important to correctly calibrate the thermometer if possible. If the thermometer cannot be calibrated, it is often possible to adjust the object using black or even tape to achieve the necessary characteristics. This term concerns the ability of the object to emit infrared radiation compared to the black body. The lower the emissivity of the object, the worse the emitting of infrared radiation. This means that if they have two objects that have lower emissivity, they will emit less infrared radiation. In order to get the most accurate IR temperature measurement, it is necessary to take into account.
In order to get the best results from the IR temperature measurement, a number of different techniques can be used. One tip for obtaining accurate IR temperature measurement involves ensuring the thermometer in good condition. The batteries should be in good condition and the lens must be clean and without restrictions. If the thermometer has manual settings, it is important for those who are also to be set correctly. Many top, non -contact IR thermometers allow the operator to enter the object's emissivity value, which can allow the most accurate reading.
If an object has an unknown emissivity or an adjustable thermometer is not sometimes possible to accurate IR temperature measurement. In the case of an object with unknown emissivity, it is sometimes possible to change the surface with something that has a known value of emissivity. If the thermometer is not adjustable, then the surface should be treated to fall within its specified emissivity range. In many cases this can be achieved by paintingan object with a flat black color or by connecting a piece of black tape.
other factors such as the wind can also affect the IR temperature measurement. The wind can cause convective heat transfer actually cooling of warm objects and heating cold. This effect cannot be easily taken into account by a non -contact thermometer, but there are several ways to get more accurate measurements. If the object can be protected from the wind, then measurement of the protected part of the surface can provide higher accuracy. Large objects can also be measured on the side of the wind to provide a somewhat more accurate result.
