5-3.About the Wavelength of Heat Radiation

An object with an absolute temperature of 0K (Kelvin) or higher radiates a wavelength corresponding to the temperature of the object as an electromagnetic wave. The object that received this electromagnetic wave has received heat. This transfer of heat is ...

3-6.Halogen Line Heater cooling

Continuous use of halogen line heaters always requires cooling. This is because the heat resistance temperature of the lamp seal is 300°C. Avoid using it at the heat-resistant temperature limit, and be sure to cool it down. If user heat ...
