What elements must to be taken into account while selecting an infrared thermometer?
What factors should be considered when choosing an infrared thermometer?
The following factors should be considered
a) type
According to site requirements, optional handheld (portable) or fixed (online).
Handheld thermometer features: small size, light weight, battery-powered, suitable for carrying around, can detect and record the temperature at any time, with optical or laser aiming device, the operation is very simple, just pull the trigger lightly, the Capable of temperature measurement.
Features of the fixed thermometer: it is fixedly installed on the industrial site, it can be monitored continuously for 24 hours, connected with the computer, and closed-loop controlled. With the addition of a protective cover and air-cooling and water-cooling devices, it can work in harsh environments and high temperatures of 315°C.
b) Temperature measurement range
The measuring range of the thermometer should meet the requirements of use.
c) Distance factor
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 the coefficient, the higher the optical resolution of the pyrometer. That is to say, when measuring the same object, the thermometer with a larger distance coefficient can measure at a farther distance.
Generally speaking, a thermometer with a large distance coefficient has high sensitivity and a higher price.
d) Minimum target
When the measured object is small, it is necessary to consider whether the minimum measurement target of the thermometer can meet the requirements of use.
