STF1500.120 is the 120 mm OD 1-zone version of Across International's STF1500 top-open tube furnace series. The live Across page describes this series as using Mitsubishi (Japan) high-quality alumina fiber insulation and silicon carbide (SiC) heating elements inside a dual-wall steel internal housing to help minimize heat loss to the exterior surface.

Furnace operation is controlled by a Eurotherm (UK) digital multi-segment controller with built-in digital communication port, allowing PC-based remote control, monitoring, and export of test results. Across notes that multiple atmosphere processes can be performed in a single cycle, such as binder burn-out in air followed by sintering under rough vacuum or inert gas.

Features

• Compact, portable, and lightweight design.
• Standard package includes stainless steel vacuum sealing flanges with valves and pressure meter.
• Microprocessor-based self-tuning PID control for stable thermal processing with minimal overshoot.
• Built-in ammeter, dual voltmeters, and computer interface.
• CE compliant on the standard listing.

Safety

• Overheat protection shuts the furnace down if temperature is outside the acceptable range or the thermocouple malfunctions.
• Power-failure protection resumes furnace operation from the interruption point once power is restored.
• Across warns never to fill the furnace with explosive gases, including hydrogen, carbon monoxide, and methane.
