First of all, quality is one of the key factors in determining the service life of thermal imaging. Quality thermal imagers are usually built with high-quality infrared detectors and other key components that provide a longer service life.
Secondly, the conditions of use also have an impact on the life of the thermal imaging camera. If used in harsh environmental conditions, such as extremely high or low temperatures, humid environments, corrosive gases, etc., a thermal imager may be damaged or degraded prematurely due to environmental factors.
Lastly, regular maintenance and care are also important to extend the life of the thermal imaging camera instrument. Regular calibration, cleaning, and maintenance will ensure that the thermal imager works properly and reduce the probability of malfunction and damage.
Overall, thermal imaging cameras typically have a life expectancy of 5 to 10 years if they are properly used, maintained and serviced. However, it is important to note that this is only a rough estimate, and the actual service life will be affected by other factors.
