Environmental Conditions to Consider When Using a Handheld Infrared 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. When the ambient temperature is high and there is dust, smoke and steam, the protective cover, water cooling, air cooling system, air purger and other accessories provided by the manufacturer can be selected.
These accessories can effectively address environmental influences and protect the thermometer for accurate temperature measurement. When specifying accessories, standardize service should be requested as much as possible to reduce installation costs. When smoke, dust or other particles reduce the measurement energy signal under noise, electromagnetic field, vibration or inaccessible environmental conditions, or other harsh conditions, the fiber optic dual-color thermometer is the best choice. Under noise, electromagnetic field, vibration and inaccessible environmental conditions, or other harsh conditions, it is advisable to choose a fiber optic colorimetric thermometer.
In applications with sealed or hazardous materials such as containers or vacuum chambers, the pyrometer views through a window. The material must be strong enough and pass through the operating wavelength range of the pyrometer being used. Also determine whether the operator also needs to observe through the window, so choose the 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. For example, an optical material that transmits both infrared radiation and visible light should be used as the window material, such as ZnSe or BaF2.
When there is flammable gas in the working environment of the thermometer, an intrinsically safe infrared thermometer can be selected to perform safe measurement and monitoring in a certain concentration of flammable gas environment.
In the case of harsh and complicated environmental conditions, a system with a separate temperature measuring head and display can be selected for easy installation and configuration. The signal output form matching the current control equipment can be selected.
