(*1) Emissivity:
An object’s ability to emit or absorb energy. Perfect emitters have an emissivity of 1. An object with emissivity of 0.8 absorbs 80% and reflects 20% of the incidental energy. Emissivity may vary with temperature and spectral response (wavelength).

(*2) Distance to spot ratio (D:S)
The infrared thermometer focuses infrared energy form an object onto its detector at the rate. 10:1 distance to spot ratio means that the infrared thermometer will read 50mm diameter area 500mm away. (The measuring spot is defined on the basis of the area that receives 90% or more of the energy)

 

(*3) Spectral Response:
The specific wavelength region where an infrared thermometer responds (in the 0.7 to 20μm band of the electromagnetic spectrum). Instrument response is dependent on the emissivity, reflectance, and the transmission of infrared energy. A spectral response in the range of 8 to 14μm is good for general use.

Positional Relation between Distance and Sighting Point

This is a one-point laser-sighting thermometer. The laser mark is sighted approximately 14 mm below the center of the spot.

(When the distance is approximately 280 mm)

When the measurement distance is approximately 280 mm, the laser marker is output aiming at the point illustrated above. Refer to the figure as a guide.
