Consider the environmental conditions when measuring the temperature of the thermometer:
The environmental conditions of the thermometer have a great influence on the measurement results, which should be considered and properly resolved, otherwise it will affect the temperature measurement accuracy and even cause damage to the thermometer. When the ambient temperature is too high and there is dust, smoke and steam, the protective cover, water cooling, air cooling system, air blower and other accessories provided by the manufacturer can be selected. These accessories can effectively solve the environmental impact and protect the thermometer to achieve accurate temperature measurement. When determining accessories, standardized services should be requested as much as possible to reduce installation costs. When smoke, dust or other particles degrade the measured energy signal, a two-color thermometer is the best choice. Under noise, electromagnetic field, vibration or inaccessible environmental conditions, or other harsh conditions, the fiber optic two-color thermometer is the best choice.
In applications with sealed or hazardous materials such as containers or vacuum chambers, the thermometer views through a window. The material must be strong enough and pass through the operating wavelength range of the pyrometer being used. It is also necessary to determine whether the operator also needs to observe through the window, so the appropriate installation location and window material should be selected to avoid mutual influence. In low-temperature measurement applications, Ge or Si materials are usually used as windows, which are opaque to visible light, and the human eye cannot observe the target through the window. If the operator needs to pass through the window target, an optical material that transmits both infrared radiation and visible light should be used, such as ZnSe or BaF2, etc. should be used as the window material.
