The Influence of the Ambient Temperature on an Infrared Thermometer
When using infrared temperature measurement to measure the temperature of an object, we inevitably have to consider external factors. The most obvious one is undoubtedly the environment. There are some new technologies in terms of environmental conditions. Let's talk about the impact of environmental conditions on thermometers.
The environmental conditions in which infrared temperature measurement is conducted have a significant impact on the measurement results and should be considered and appropriately addressed, otherwise it may affect the accuracy of temperature measurement and even cause damage to the thermometer.
1, The Influence of Environmental Temperature on the Performance of Infrared Thermometers
The ambient temperature is divided into two situations: one is the environment of the measured target, and the other is the ambient temperature of the infrared thermometer's residence. If the background temperature of the target being measured is higher than or close to the temperature of the target being measured, it will affect the measurement results. When the ambient temperature of the infrared thermometer exceeds the range that the thermometer can withstand, it will also affect the temperature measurement results.
2, The influence of humid environment on the performance of infrared thermometer
A humid environment can cause internal short circuits in the thermometer, which in turn can affect the measurement results.
3, On site factors for temperature measurement with a thermometer:
(1) Measure the angle and ensure it is within the allowable range;
(2) Are you aiming correctly
(3) Is the selected spectral range (wavelength) appropriate? When measuring targets in containers with glass windows, the spectral range should not be selected between 8-14 μ m, but around 1 μ m;
4, Measurement of targets in strong light background:
If the target being measured has a relatively bright background light (such as sunlight or direct sunlight), the accuracy of the measurement will also be affected. Therefore, objects can be used to block the strong light of the direct target to eliminate the interference of background light and the impact on the measurement results.
