ترمومتر لیزری VC303B
Description:
An
infrared thermometer is a thermometer which infers temperature from a
portion of the thermal radiation sometimes called black-body radiation
emitted by the object being measured. They are sometimes called laser
thermometers as a laser is used to help aim the thermometer, or
non-contact thermometers or temperature guns, to describe the device's
ability to measure temperature from a distance.
Every
infrared thermometer has a "distance-to-spot" (D:S) ratio that tells you
the diameter of the area being measured compared to the distance from
the target. For example, if your thermometer has a distance-to-spot
ratio of 12:1, it measures an approximately one-inch-diameter spot when
it's 12 inches from the target (about 2.5 cm to 30 cm).
Most handheld
infrared thermometers have laser pointers that show the approximate
center of the measurement area. It's important to know that the laser is
only a pointer and not used for the actual temperature measurement.
