Factors Leading to Damage of Infrared Thermometers
The main performance indicators of infrared thermometers include spectral response, response time, repeatability, and emissivity. Fixed infrared thermometers are used in the glass and ceramic industry, paper and packaging industry, various kiln temperature measurement applications, and chemical industry to measure the temperature of instruments and meters, in order to detect the operating status of instruments and ensure their normal operation.
Factors causing product damage:
The first type: moisture factor
Infrared thermometers are usually affected by factors such as moisture, rain, dew, etc. Dew formed by moisture is the main factor causing outdoor humidity. Dew is more harmful than rain because it adheres to materials for a longer period of time, causing more severe moisture absorption. If the surface aging layer of the wood coating is removed by rainwater washing, the unaged inner layer will be exposed to sunlight, resulting in further aging. In the simulation experiment of infrared thermometer, the mechanism of composite material damage caused by humid environment has been well studied. Taking the diffusion of moisture into carbon fiber epoxy resin laminates as an example, this paper illustrates the aging mechanism of composite materials in humid atmospheric environments.
Second type: lighting factor
The structural composition of different products of infrared thermometers also varies in terms of the intensity of light exposure. For example, durable materials such as plastics, coatings, etc., when exposed to light, do not experience severe aging. So it is necessary to analyze the material composition of the product equipment.
The third type: high temperature factor
When the surrounding temperature rises due to high temperature, it will increase the intensity of light and the degree of damage. There is no direct chemical reaction between temperature and light, but there is a subtle connection between them. So when testing programmable infrared thermometers, it is important to grasp the precise temperature range of use.
These three factors are crucial for the impact of product equipment, and any one of them can quickly shorten the service life of the thermometer.
