IRQWD

IRQWD Series Dual-Color Pyrometer with Center Laser Aiming

IRQWD Series

The IRQWD Dual Color High Performance Online Infrared Pyrometer is an advanced non-contact temperature measurement system designed for demanding industrial applications. Using two-color ratio pyrometry technology, the instrument delivers reliable and accurate temperature measurement even when the target emissivity varies or the target is partially obstructed. With integrated laser aiming, fast response time, and robust industrial design, the IRQWD series ensures precise temperature monitoring for critical high-temperature processes.

  • Reliable measurement even with emissivity variations using dual-color sensing
  • Accurate readings when the target is partially obstructed or smaller than the spot size
  • Fast temperature response for rapidly changing industrial processes
  • Precise targeting with built-in laser aiming system
  • Stable and repeatable measurements for critical process control
