Therefore, for the equipment under testbreakdownRelated partstemperatureofCalculation and reasonable correction is to improve the surface of testing equipment.temperatureThe key link of accuracy. But in the field.equipmentinfraredWhen testing, due to the detection conditions andenvironmentThe influence of change, may lead to the same equipment due to test strip.Different pieces, and get different results. Therefore, in order to improveinfraredThe accuracy of detection must be checked on site.measureprocessOr in the analysis and processing of the test results, take corresponding countermeasures and measures or choose good tests.Conditions, or make reasonable corrections to the test site results. Generally, we need to follow the following conditions and influences.Specific applicationinfrared radiation thermometer:
