Heat Treatment Furnace Inspection

Covering numerous fields such as aviation, aerospace, automotive, petroleum, forging, aircraft, and machining.

Our independently developed furnace temperature testing system, the "Black Box," features numerous advantages such as high-temperature resistance, long duration, and compact size. The measurement range is (0–1350)°C, with an adjustable sampling interval of (0.1–3600) seconds. It is suitable for various continuous furnaces, semi-continuous furnaces, car-bottom furnaces, walking beam furnaces, and vacuum furnaces.
