uIRt/c.SV is a micro sized non-contact infrared type k thermocouple that reads at a right angle. It has a 1:2 field of view, stainless steel body and it's self-powered so no additional power source is required for use. The low price makes this an ideal option for OEMs.
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 pre-calibrated 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 uIRt/c.SV-K-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) |
