1000℃ Three-Zone Tube Furnace with 310S Stainless Steel Tube

Product Description

The three-zone tube furnace (1000℃, 310S stainless steel tube) is designed for precise heat treatment and thermal processing of materials in laboratories and industrial R&D.
It features three independent heating zones for accurate temperature distribution, water-cooled flanges, and high thermal uniformity, making it ideal for annealing, sintering, and atmosphere-controlled experiments.

With ±1℃ temperature accuracy, ±3℃ uniformity, and a programmable 30-segment controller, it ensures reliable operation under vacuum (-0.1 MPa) or controlled gas atmospheres.
Suitable for ceramics, metallurgy, materials science, powders, and high-performance alloys.
