• Temperature range:
  -40°C to 975°C
• Spectral range: 8 to 14 µm
• Response time: 100 ms

Applications:

Due to its unique stainless steel measuring head, capable of resisting temperatures of up to 250°C, the infrared thermometer optris CThot LT can be universally employed for the measurement of non-metallic surfaces in hot surroundings.

It is suitable for use in driers and ovens, tempering facilities of metal and glass industries, plastics and textile processing, and semiconductor production.

infrared software optris Compacts Connect included:

The temperature analysis software optris Compact Connect has been developed specifically for the extensive documentation and analysis of temperature measurement data of our stationary infrared thermometers. It is license-free and included in every pyrometer shipment.
