Understanding Infrared Thermometers
Infrared thermometers are widely used in various industries for temperature measurement applications. They use a non-contact method of measurement and can measure temperature from a safe distance. These thermometers work on the basis of detecting and measuring the amount of infrared radiation emitted by an object.
In this article, we will discuss the precision of infrared thermometers compared to other types of thermometers.
How precise are Infrared Thermometers?
The accuracy of an infrared thermometer depends on various factors such as its distance from the object being measured, the emissivity of the object, and the temperature range being measured. However, in general, infrared thermometers are considered to be less accurate than contact thermometers.
The accuracy of an infrared thermometer can be affected by factors such as humidity, air temperature, and air movement. Therefore, it is important to use these thermometers in the correct conditions and to follow the manufacturer’s instructions for use.
Comparison with Contact Thermometers
Contact thermometers, also known as probe thermometers, are considered to be more accurate than infrared thermometers. This is because contact thermometers measure the temperature of an object by coming into physical contact with it.
Contact thermometers can be of various types including digital thermometers, liquid-filled thermometers, and bimetallic thermometers. The accuracy of these thermometers depends on their design and calibration.
Application-Specific Precision
However, infrared thermometers are more suitable for certain applications such as measuring the temperature of moving objects, inaccessible objects or objects that emit harmful radiation. In these cases, contact thermometers would not be able to provide accurate readings.
Moreover, infrared thermometers are much faster than contact thermometers and can provide temperature readings in just a few seconds. This makes them ideal for applications where speed is important.
In conclusion, while infrared thermometers may not be as accurate as contact thermometers, they are still useful for specific applications. It is important to consider the type of application before choosing which thermometer to use. In the end, the precision of the thermometer depends on its design, calibration, and conditions of use.
