Distance coefficient(optical resolution):distance coefficient is the ratio of "D" (the
distance between head and the object) and the diameter of the object. If the distance to the
object is far, and the object is small, you should choose the high distance coefficient
thermometer, on the other hand, you should choose low distance coefficient thermometer.
Confirming response time::Response time express the response speed that the
infrared thermometer responses to the temperature being measured, defined as the time
needed that arrive 95% of the last reading power It has relations with photo-electric
detector, signal process circuit and the time constant of display system If the speed of
moving object is very quick and measuring the object that heated quickly, you should
choose the high-speed response infrared thermometer, otherwise, it won't achieve the
enough signal response speed and will lower the measuring accuracy. But not all of
applications need quick response infrared thermometer. To the quiescent object or the
object that on the course of heat has heat inertia, the response time can be loosen.
Therefore, the infrared thermometer's selection must be adapted to the state of the
object.
Confirming circumstance:The circumstance of the thermometer will affect the
measuring result a lot., so the problem should be considered and be solved properly,
otherwise, this will affect the accuracy of thermometer even damage the thermometer。
On the conditions of high temperature, existing dust, smoke and steam, you should
choose the accessories supplied by factory such as protect cover, water-cool, air-cool,
air-cool system, air-blow etc These accessories can solve circumstance influence
effectively and protect the thermometer, realizing temperature measuring exactly. When
choosing accessory, you should request standard service as far as possible to reduce the
cost of setup. It would be the best to choose bicolor infrared thermometer on the
conditions of smoke, dust or other situation that grain will lower the power of measuring
signal. Also, on the conditions of noisy, electromagnetic field, shaking or the circumstance
that difficult to be closed or other bad conditions, bicolor infrared thermometer is the best.
On the conditions of bad and complex, choosing the system that the thermometer head
and the monitor is divided is convenience to setup and equip. You should choose the
signal modality that matching the control equipment actual
Emissivity of material(emissivity):When there are many kinds of material measured
and their emissivity is different, it's better to choose the infrared thermometer that the
emissivity is adjustable.
