QUESTIONS & ANSWERS
The laser spot needs to be showing inside the target area. An 8:1 distance-to-spot ratio means you are measuring a 1" diameter area at a distance of 8".
Distance is unlimited. The size of the target area sets the limit on distance for accurate measurements. For example, if the area you wish to measure is 1 foot in diameter, then you will need to be within 8 feet to record an accurate temperature.
Approximately one-half inch in diameter.
Emissivity is the ratio of an object's infrared emission compared to a theoretical black body considered 1. Emissivity is always less than 1.
Adjustable emissivity allows your non-contact thermometer to be adjusted to the surface you are checking to ensure more accurate readings.
