1200°C Top-Loading Crucible Furnaces are ideal for use in ceramics, electronics, glass, metallurgy and superconductor materials research. Unitized heating and insulation element with helical wire coil imbedded in MoldathermŪ insulation for maximum heat transfer to the work load. PlatinelŪ II thermocouple with 10'compensated lead wire and polarized plug for long life and accurate temperature measurement. MoldathermŪ ceramic fiber hearthplate supports load and protects furnace from spillage. These models require independent controllers (ordered separately). Three types of controllers are available. Digital Single Set-Point Program Controller (F5130-5) 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. Simultaneous LED display of actual temperature vs. setpoint. May be configured to display temperature in either °C or °F. Digital Single Program Multi-Segment Programmable Controller (F5130-6) has the same features as F5130-5 with the addition of single program with multiple segments for ramp (up and down) and dwell (timed hold) temperature control. Simultaneous LED display of actual temperature vs. setpoint. May be configured to display temperature in either °C or °F. F5130-7 is the same as F5130-6 with the addition of Built-in adjustable high limit OTC (overtemperature protection). RS485 Digital communications port available as an option. Allows controller to be connected to a PC for remote monitoring and control of the furnace. Up to 30 units can be connected to one PC. All models are 208/240V.
