The resolution of the infrared temperature measurement

When the tape or paint reaches the same temperature as the substrate material, the temperature of the tape or paint surface is measured, that is, the real temperature thereof. The optical system of the distance and the spot, the optical system of the infrared thermometer collects energy from the circular measuring spot and focuses on the detector, the optical resolution is defined as the distance between the infrared thermometer to the object and the ratio of the spotted spot (D) : S).

The greater the ratio, the better the resolution of the infrared thermometer, the smaller the size of the spotted spot. Laser is aimed, only use to help a targeting the infrared temperature gauge on the measurement point. The latest improvement in infrared optical is to increase the near focus characteristic '' to provide accurate measurements for small target areas, and also prevent the effects of background temperature. The field of view ensures that the target is larger than the infrared thermometer measurement, the smaller the target, the closer it. When accuracy is extraordinary, it is necessary to ensure that the target is at least 2 times the spot size.
