IRQ

IRQ Series Dual-Color Online Infrared Pyrometer

IRQ Series

The IRQ Dual Color Online Infrared Thermometer is a high-performance non-contact temperature measurement system designed for extreme industrial environments. Using two-color ratio pyrometry technology, the IRQ series provides accurate and stable temperature measurement even in challenging conditions such as smoke, dust, steam, or fluctuating emissivity. With high optical resolution, robust industrial design, and multiple targeting options, it is ideal for critical high-temperature applications.

  • Accurate measurement even in harsh environments with smoke, dust, or steam
  • Reduced influence of emissivity variations using two-color ratio technology
  • Reliable measurement even when the target does not fully fill the field of view
  • Flexible installation with long-distance measurement capability
  • Highly stable readings for critical industrial process control

    Frequently Asked Questions About This Product

    A dual-color infrared thermometer measures temperature using the ratio of radiation at two wavelengths, allowing accurate measurement even when emissivity changes or the view is partially obstructed.
    Two-color pyrometers provide reliable readings in difficult conditions such as smoke, dust, steam, partially obstructed targets, or small targets that do not fill the sensor’s field of view.
    Depending on the configuration, the IRQ series can measure temperatures from 200°C up to 3000°C.
    Common industries include steel manufacturing, forging, heat treatment, induction heating, vacuum furnaces, and high-temperature metallurgical processes.
    Yes. The IRQ pyrometer supports 4–20 mA analog output and optional RS485 Modbus communication, enabling integration with PLC, DCS, and SCADA systems.
