How to Care for and Maintain an Infrared Thermometer
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 industries, papermaking and packaging industries, various kiln temperature measurement applications, and the chemical industry to measure the temperature of instruments and meters to detect the operating status of the instruments and ensure the normal operation of the instrument. run.
Factors leading to damage to online thermometers include the following:
The first type: moisture factor. Infrared thermometers usually use moisture, rain, dew, etc. as factors that cause moisture. Dew formed by moisture is the main factor in outdoor moisture. Dew causes greater harm than rain because it adheres to materials. Leaving it on longer will cause more severe moisture absorption. For example, the surface aging layer of a wood coating is removed by rainwater, exposing the unaged inner layer to sunlight, resulting in further aging. In the infrared thermometer simulation test, the damage mechanism of composite materials caused by humid environment has been clearly studied. The diffusion of moisture into carbon fiber epoxy resin laminates is taken as an example to illustrate the aging mechanism of composite materials in a humid atmospheric environment.
The second type: lighting factors. The structure of different products of infrared thermometers also has different intensity of light. For example, those durable materials, such as plastics, paints, etc., will not cause serious aging when exposed to light. Therefore, it is necessary to analyze the material composition of the product equipment.
The third type: High temperature factor: When the surrounding temperature increases due to high temperature, the intensity of light and the degree of damage will increase. There is no direct chemical reaction between temperature and light, but there is a subtle connection between them. Therefore, when testing programmable infrared thermometer products, it is necessary to grasp the precise temperature range.
These three factors are crucial to the impact of product equipment. Any one of them can quickly shorten the service life of the thermometer.
Infrared thermometer studies have shown that water-induced reduction in the modulus of epoxy resins is reversible. When the external environment changes and the moisture diffuses out, the film content of the resin can almost return to its original value. However, for many water absorption processes, the property changes caused by water are irreversible. Irreversible changes will lead to a significant reduction in the physical and mechanical properties of the material. At the same time, a programmable infrared thermometer can simulate the humid atmospheric environment to detect the anti-aging properties of the material. Therefore, we must pay more attention to details when operating online thermometers in order to better use such instruments.
