Advantages and Disadvantages of Infrared Thermometers
Infrared thermometers can quickly and conveniently measure the surface temperature of objects through non-contact methods. Infrared thermometers are mainly used to measure high temperature, dangerous or difficult to contact objects. What are its main advantages and disadvantages? Let's take a closer look below.
Advantages
1. Non contact measurement: It does not require contact with the interior or surface of the measured temperature field, so it will not interfere with the state of the measured temperature field, and the thermometer itself is not damaged by the temperature field.
2. Wide measurement range: As it is a non-contact temperature measurement, the thermometer is not located in a high or low temperature field, but works under normal temperature or conditions allowed by the thermometer. In general, it can measure negative tens of degrees to over 3000 degrees.
3. Fast temperature measurement speed: i.e. fast response time. As long as the infrared radiation of the target is received, the temperature can be set in a short period of time.
4. High accuracy: Infrared temperature measurement does not damage the temperature distribution of the object itself like contact temperature measurement, so the measurement accuracy is high.
5. High sensitivity: As long as there is a small change in the temperature of an object, the radiation energy will change significantly, making it easy to measure. It can perform temperature measurement and temperature distribution measurement of small temperature fields, as well as temperature measurement of moving or rotating objects. Safe to use and long service life.
Disadvantages
1. Easily affected by environmental factors (such as ambient temperature, dust in the air, etc.)
2. The temperature reading of bright or polished metal surfaces has a significant impact
3. Limited to measuring the external temperature of the object, not convenient for measuring the temperature inside the object and in the presence of obstacles
