Several aspects to consider when choosing an infrared thermometer
(1) Determine the temperature measurement range: The temperature measurement range is the most important performance index of the thermometer. Each type of thermometer has its own specific temperature range. Therefore, the user's measured temperature range must be considered accurately and comprehensively, neither too narrow nor too wide.
(2) Determine the target size: when measuring temperature, the area of the target to be measured should fill the field of view of the thermometer. It is recommended that the measured target size exceed 50% of the field of view. If the target size is smaller than the field of view, background radiant energy can interfere with the reading, causing errors. Conversely, if the target is larger than the pyrometer's field of view, the pyrometer will not be affected by background radiation outside the measurement area.
(3) Accuracy: Choose any instrument, which of course must be considered. Infrared thermometer is no exception. The choice should also be considered comprehensively, not the higher the better. To meet your own requirements and within the cost budget as well.
(4) Determining the optical resolution The optical resolution is determined by the ratio of D and S, which is the ratio of the distance D between the thermometer to the target and the diameter S of the measuring spot. If the thermometer must be installed far away from the target due to environmental conditions, and a small target is to be measured, a thermometer with high optical resolution should be selected
(5) When determining the response: The response time indicates the reaction speed of the infrared thermometer to the measured temperature change. If the target moves quickly or measures a rapidly heating target, a fast-response infrared thermometer is required. For static or target thermal processes where thermal inertia exists, the response time of the pyrometer can be relaxed. Therefore, the choice of the response time of the infrared thermometer should be adapted to the situation of the measured target.
(6) Consideration of environmental conditions: The environment where the thermometer is located has a great influence on the measurement results. When the ambient temperature is too high, there is dust, and other conditions, you can choose the protective cover and other accessories provided by the manufacturer. These accessories can effectively address environmental influences and protect the thermometer for accurate temperature measurement.
