IRP 1R/2R Series Two-Color Portable Infrared Thermometer

IRP 1R/2R Series

The IRP 1R / 2R Two-Color Portable Infrared Thermometer is a handheld high-performance non-contact temperature measurement device designed for demanding industrial applications. Using ratio (two-color) infrared thermometry, the instrument delivers accurate and stable measurements even when emissivity changes or the target is partially obscured by dust, smoke, steam, or dirty viewing windows. With high optical resolution, visual sighting optics, and built-in data logging, the IRP series is ideal for high-temperature field inspections and process verification.

Accurate measurement despite emissivity variations using ratio pyrometry
Reliable readings even through dust, smoke, steam, or dirty viewing windows
High optical resolution (up to 250:1) for measuring small targets from a distance
Portable handheld design for field inspection and troubleshooting
Data logging and USB connectivity for measurement analysis

Frequently Asked Questions About This Product

A two-color infrared thermometer measures temperature using two wavelengths of infrared radiation and calculates temperature based on the ratio between them. This makes measurements less sensitive to emissivity changes.

Two-color pyrometers are ideal when: the target is partially obstructed by dust or smoke, emissivity changes during the process, target is small compared to the measurement spot, and viewing window becomes dirty over time

Depending on the model, the device can measure temperatures from 400°C up to 3000°C.

Yes. The instrument can store up to 1000 temperature readings, which can be downloaded via USB interface.

Typical industries include steel plants, forging industries, furnace operations, metallurgy, and research laboratories.
