Scope of Application

【Operating Instructions】

The chamber is made of special ceramic fiber material, offering light weight, low heat capacity, and low heat loss when empty. Compared with older‑type resistance furnaces, it saves more than 70% of energy. The heating rate is fast and adjustable. It is programmable to meet 30–50 segments of continuous temperature control and constant temperature holding, enabling timed automatic heating and constant‑temperature operation. It features PID auto‑tuning, interference‑free switching between manual and automatic modes, and over‑temperature alarm.
