IR Thermometers

Compare IR THERMOMETERS that detect the IR emission of a spot some distance from the thermometer. The optics of the IR thermometer will determine the spot size that will be measured at a given distance, called the distance to spot ratio. The distance from the IR source may be a few inches or a few feet.

Thermal Imaging Cameras

Compare THERMAL IMAGERS that measure the thermal (IR) radiation of every point in an image. Every object emits thermal electromagnetic waves in the infrared region. The amount of energy emitted depends on the temperature and the material properties of the object. The ability of any material to emit infrared waves is called the emissivity
