Explanation of Factors to Consider When Choosing an Infrared Thermometer
a) Type
According to on-site requirements, players can hold it (portable) or fix it (online).
Handheld thermometer features: small size, light weight, battery powered, suitable for carrying around, can detect and record temperature at any time, with optical or laser aiming devices, easy to operate, just lightly pull the trigger to measure temperature.
Characteristics of fixed thermometers: They are fixedly installed on industrial sites, can monitor continuously for 24 hours, are connected to computers, and have closed-loop control. By installing protective covers and air and water cooling devices, it can work in harsh environments and high temperature conditions of 315 ℃.
b) Temperature measurement range
The measuring range of the thermometer should meet the requirements for use.
c) Distance coefficient
The distance coefficient D: S is the ratio of the distance between the thermometer and the object being measured to the diameter of the object being measured. The larger this coefficient, the higher the optical resolution of the thermometer. A thermometer with a larger distance coefficient can measure the same object at a greater distance.
Generally speaking, thermometers with high distance coefficients have higher sensitivity and are also more expensive.
d) Small target
When the measured object is small, it is necessary to consider whether the small measurement target of the thermometer can meet the usage requirements.
