CF1700.20.20.20 is the 20 x 20 x 20 inch chamber variant from Across International's CF1700 multi-segment muffle furnace series. The live Across page describes this series as using Mitsubishi (Japan) high-quality grade 1800 alumina fiber insulation and molybdenum silicide (MoSi2) heating elements inside a dual-wall steel housing to help minimize heat loss.

Furnace operation is controlled by Shimaden (Japan) digital control with RS485 communication and USB adapter for PC-based remote control, monitoring, and export of test results. Across also lists controller options for the Eurotherm 3204 8-segment programmer and optional Eurotherm 3504 50-segment programmer.

Features

• Microprocessor-based self-tuning PID control for optimum thermal processing with minimal overshoot.
• Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
• Built-in computer interface.
• Long-life type B thermocouple.
• 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.
