Different blackbody geometry and distance of measurement influence on the calibration results of hand infrared thermometers.
Original language description
Portable hand infrared thermometers are very popular at end users level for common measurements. A lot of types with big variety of their properties are available on the market. As a key condition for proper temperature measurement looks to perform measurement from right distance with an object with sufficient dimensions. Manufacturers provide information how the measurement spot should changes with a distance. Otherwise, no information about the change of temperature in dependency on the distance is provided. Aim of presented work was investigate how the result of calibration may vary when different types of the blackbodies are used and when the measurement distance is changing. Three blackbodies were used for measurements: heat pipe blackbody, blackbody with spherical cavity and common flat plate blackbody. Presented case study was performed at 3 thermometers at least, with different optic specification, working in wavelength range (8 to 14) ?m. Measurements were performed at differe
