The STI C-080 Pyrometer is a handheld Service Tectonics (STI Model C Gage) temperature instrument with a measurement range of 0–800°F and catalog number 801245. Some listings depict this unit as meter-only, sold without a probe or manual, indicating that a separate sensor probe is required for actual temperature sensing. Historical references show that Service Tectonics offered analog pyrometers, and the C-080 designation appears in vintage STI product listings for the Model C Gage line.
