A. FPA Thermal Imagers provide a real time thermographic image of the entire component. Spot radiometers only measure specific points. Q: How close do I have to be to an object to take its temperature? A: Distance does not affect the measurement. However, infrared sensors measure the energy from a circular spot on the target, and the size of that spot is a function of the distance between the sensor and target. The farther away from the target the sensor is, the larger the spot. Consequently, distance is only limited by the size of the object you want to measure. Q: Can the object or product being measured be moving? A: Yes. Measuring moving targets is one of the benefits of using noncontact infrared thermometers.
