Designed for high temperature metallurgical, ceramic, chemical and electronic research. Furnaces use independent digital temperature control modules (ordered separately) which are available in standard or programmable varieties with an optional communications port. Double-end silicon carbide heating elements mounted above and below the chamber. Heating elements cross the chamber at right angles with compressed spacing at ends to offset heat loss from end of process tube. Removable side panels for easy installation and electrical connection, simplified heating element replacement and adjustment. High temperature insulation with insulated end vestibules for better uniformity and energy efficiency, long life, fast response type R thermocouples with 10 ft compensated lead wire and polarized plug. Digital control console is fully wired and includes advanced microprocessor-based digital control, a solid-state power module, on/off circuit breaker and thermocouple input jack. Includes microprocessor-based PID control (proportional, integral, derivative), single segment, single setpoint, 1 ramp to setpoint. Built-in adjustable high limit overtemperature protection. Simultaneous LED display of actual temperature vs. setpoint. May be configured to display temperature in either °C or °F. Digital 16 segment programmable controller also features 1 program with 16 segments for ramps (up and down) and dwells (timed holds). Built-in adjustable high limit overtemperature protection.
Three zone model features independent power circuits (zones) with independent thermocouples for control references with full adjustment of each zone over entire operating range. Center zone uniformity achieved and operating length maximized through adjustable profiling of end zones by independent controller. Controlled temperature uniformity achieved with independent setpoint of end zones higher or lower than center zone. Temperature range: 500° to 1500°C (932° to 2732°F). 208/240V, 50/60 Hz.
