When choosing an infrared thermometer, what factors should I consider?
The following factors should be considered
a) Type
According to on-site requirements, contestants can hold (portable) or fixed (online).
Features of handheld thermometer: small size, light weight, battery powered, suitable for carrying around, temperature detection and recording can be carried out at any time. It has optical or laser aiming devices, and the operation is very simple. With just a light pull of the trigger, temperature measurement can be carried out.
Features of fixed temperature measuring instrument: It is installed on industrial sites and can continuously monitor 24 hours. It is connected to a computer and has closed-loop control. Equipped with protective sleeves and air-cooled and water-cooled devices, it can work in harsh environments and high temperature conditions of 315 ℃.
b) Temperature measurement range
The range of the thermometer should meet the usage requirements.
c) Distance coefficient
The distance coefficient D: S is the ratio of the distance between the thermometer and the measured object to the diameter of the measured object. 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 further distance.
Generally speaking, thermometers with large distance coefficients have high sensitivity and higher prices.
d) Minimum 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.
