The IRt/c.3X is a non-contact infrared thermocouple with K and J thermocouple outputs. It's self-powered so no additional power source is required for use.
The IRt/c.3X comes equipped with an integral air purge which makes this sensor great for applications where the environment contains paint or ink that might interfere with the line of sight.
IRt/c’s are pre-calibrated at the factory for typical target material emissive properties, but actual emissivities may differ. The accuracies specified assume that the precalibrated value is correct for your installation, or that the system has been calibrated at a single point for the application. The calibration temperature is included in the part number, for example the IR-EX-IRt/c.3X-J-440F/220C is calibrated at 440°F. The error of this sensor at 10°F away from the 440°F, that is 430 or 450°F would be ± 0.4% of reading (1.7°F at 430°F)
| Target Temperature Variation | Error(greater of)* |
| 0°F (0°C) | 0% or 0.02°F (0.01°C) |
| ±5°F (± 3°C) | ± 0.2% or 0.5°F (0.3°C) |
| ±10°F (± 6°C) | ± 0.4% or 1.0°F (0.6°C) |
| ±20°F (± 12°C) | ± 1% or 2°F (1°C) |
| ±40°F (± 24°C) | ± 2% or 4°F (2°C) |
| ±75°F (± 42°C) | ± 5% or 8°F (5°C) approx. |
| ±180°F (± 100°C) | > 5% or 8°F (5°C) |
