Online Infrared Thermometer IRQWD Series

IRQWD Series

The IRQWD Series is a two color infrared thermometer with display, supplied with a separate panel-mount controller. The two-color sensor stays reliable with emissivity variations and partly obscured targets, while the panel meter shows the reading and alarms for non-contact continuous monitoring from 600°C to 1800°C.

  • Two-color ratio sensing
  • Panel display controller
  • Non-contact continuous monitoring
  • Center laser aiming
  • 4-20 mA isolated output

    Frequently Asked Questions About This Product

    It is a ratio pyrometer supplied with a panel-mount display controller. The IRQWD sensor reads the ratio of energy at two wavelengths, and the panel meter shows the value and alarms for 600°C to 1800°C measurement.
    The IRQWD is supplied with a separate panel-mount display controller and shows the reading and alarms on a panel meter, while the IRQ uses a front-panel display on the sensor body.
    The IRQWD covers 600°C to 1800°C.
    The IRQWD provides ±0.75%TH accuracy, where TH is the higher limit of the range, with ±0.2% repeatability.
    Yes. The IRQWD uses center laser aiming with a built-in laser pointer for pinpoint targeting.
    The IRQWD provides a 4–20 mA isolated output and RS485 communication, with high and low alarm indication for continuous monitoring.
    Users should check target temperature, spot size at distance, display panel size, mounting, ambient condition and output requirement.
