KF40 Flange for Infrared Temperature Measurement in Vacuum

Reliable Vacuum Insulation with Infrared Optical Window for Non-Contact Temperature Measurements in Vacuum Environments

The KF40 Flange is crucial for integrating infrared temperature sensors into vacuum systems operating down to 10^-7 mbar. KF flanges, also known as NW, QF, or DN flanges, are ISO-standardized vacuum fittings designed to create a vacuum seal by compressing a rubber O-ring between two mating surfaces. These flanges are highly valued for their ease of use, maintenance, and reusability, making them ideal for quick assembly of vacuum systems. With robust construction and reliable vacuum isolation, it is compatible with standard interfaces, providing a dependable solution for precise temperature measurements in vacuum environments. The KF40 Flange ensures the integrity of the vacuum system by effectively isolating the sensor, making it essential for high-quality, accurate applications.

  • Seals reliable down to 10^-7 mbar
  • Various infrared windows
  • Made in stainless steel
