Introduction to environmental conditions of infrared thermometer and humidity sensor
The environmental conditions in which the thermometer is located have a great impact on the measurement results and should be considered and appropriately resolved, otherwise it will affect the temperature measurement accuracy and even cause damage. When the ambient temperature is high and dust, smoke and steam are present, accessories such as protective covers, water cooling, air cooling systems, and air purges provided by the manufacturer can be used. These accessories effectively address environmental influences and protect the thermometer for accurate temperature measurement. When determining accessories, standardize services should be requested whenever possible to reduce installation costs. Optical fiber two-color thermometers are the best choice when noise, electromagnetic fields, vibration or inaccessible environmental conditions, or other harsh conditions, smoke, dust or other particles reduce the measurement energy signal. Colorimetric thermometers are the best choice. In the presence of noise, electromagnetic fields, vibration, inaccessible environmental conditions, or other harsh conditions, it is advisable to choose a light colorimetric thermometer.
In sealed or hazardous materials applications (such as containers or vacuum chambers), the thermometer observes through a window. The material must be strong enough and pass through the operating wavelength range of the thermometer used. Also determine whether the operator also needs to observe through the window, so choose an appropriate installation location and window material 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, as the window material.

When flammable gases exist in the working environment of the thermometer, an intrinsic infrared thermometer can be used to measure and monitor in a certain concentration of flammable gas environment.
In the case of harsh and complex environmental conditions, you can choose a system with separate temperature measuring head and display to facilitate installation and configuration. The signal output form can be selected to match the current control equipment.
