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.
