Distance vs Object Placement Concept:

The optical resolution (D:S) of our product is 20:1, it refers to the ratio of the measuring distance to the diameter of the measured object. When the distance between the infrared temperature sensor and the object to be measured increases, the surface area of the object to be measured is required to be larger.
