Frequently Asked Questions About This Product

A short wave infrared pyrometer measures temperature using short wavelengths such as 1µm or 1.6µm. Short wavelengths reduce measurement error on hot metal and give more accurate readings than long-wave models at high temperatures.

The range depends on the variant: 1MS covers 600°C–1600°C, 2MS covers 300°C–1300°C and 2MH covers 385°C–1600°C.

The IRK 1M/2M/2MH offers optical resolution up to 300:1, so it can read small or distant hot targets at a working distance.

Yes. It measures temperature without touching the target, which suits continuous monitoring of moving or hot metal that a contact probe cannot reach.

The IRK provides a 4–20 mA analog output and RS-485 Modbus RTU digital communication for continuous monitoring.

The response time is 5 ms, which supports fast-changing high-temperature processes.

Users should check target temperature range, spot size at distance, emissivity, mounting condition, ambient temperature and output requirement.
