IR-FAQ (300-3000℃)

• fiber optics can be used up to 150℃ without cooling
• fiber optics is not conductive, making it advantageous for use in induction heating and explosion proof environments.
• Laser projection option available for checking measurement points
• The main body is small and lightweight and can be mounted on a DIN rail.
• A wide range of models are available, including low temperature, medium to high temperature, and two-color models
