Does the environment have a big impact on the temperature measured by the thermometer?
The detector of the infrared thermometer works at ambient temperature, and its reception of infrared radiation energy will be affected by the temperature of the working environment. Each thermometer has its own normal working conditions, so during use, we should try to make it meet the working requirements. For D: S≈ Wei 2 body conditions, please refer to the relevant instructions. The infrared radiation energy of the surface of the measured target is transmitted to the infrared thermometer through the atmosphere, which is attenuated by absorption and attenuation by gas molecules such as water vapor, carbon dioxide, and carbon monoxide in the atmosphere, and by scattering by suspended particles in the air. The attenuation of radiation energy transmission increases with distance, causing the temperature displayed by the instrument to be lower than the actual temperature value of the measured target point, thus causing misdiagnosis. It can be seen that as the detection distance increases, the atmospheric impact will become greater and greater. If you want to obtain the accuracy of the target temperature, you must take the following countermeasures: Try to choose a season when the ambient atmosphere is relatively dry and clean; shorten the detection distance as much as possible without affecting the temperature; and make reasonable adjustments to the temperature measurement results. Distance correction to measure actual temperature value. For example, when testing outdoor power equipment, the infrared radiation received by the infrared thermometer includes, in addition to the radiation emitted by the corresponding parts of the equipment under inspection, reflections from other parts of the equipment and the background, as well as direct solar radiation. These radiations will cause interference to the temperature of the part of the equipment to be measured and bring errors to fault detection. Therefore, try to do it on a cloudy day or in the evening when there is no light at sunset. There are many environmental factors that affect the accuracy of temperature measurement. When using it, you can take corresponding measures based on specific accuracy requirements.
