AMS 2750 in Practice

AMS 2750 (Pyrometry) defines the requirements for temperature measurement and control in heat treatment furnaces used in aerospace manufacturing. It specifies thermocouple calibration intervals, TUS frequency by furnace class, SAT tolerances, and documentation requirements.

Our AMS 2750 tool takes you through the classification process — identifying your instrumentation type (A–E), furnace class (1–6), and qualified work zone — then calculates all required test frequencies and generates a compliance schedule. Used by engineers at Howmet Aerospace, Safran, and across the UK aerospace supply chain.
