Lindberg/Blue M* 1700°C Box Furnaces

• Designed for efficient high-temperature use with minimal maintenance
• Choice of single setpoint or programmable control
• Side swing door provides full and easy access to chamber, protects user from heat surge
• Atmosphere port, 0.375 in. diameter, for fresh air or inert gas inlet (located at back wall, bottom)
• Solid-state power module with ammeter, circuit breaker, transformer and front panel indicator lights for “Ready Element” and “Main Power Applied”
• Safety power disconnect switch cuts power to heating elements when door is opened
• Moldatherm* high-temperature ceramic fiber insulation with advanced graded design for fast heat-up and resistance to thermal shock
• Moldatherm hearthplate supports load and protects chamber from spills or mishandling
• High-volume cooling fans move air between inner and outer chamber to reduce exterior shell temperatures and improve energy efficiency and operator safety
• Long-life type “B” thermocouples with 10 ft. compensated lead wire and polarized plug for accurate high-temperature measurement
• Removable panels for easy access to replaceable heating elements and thermocouples

• Molybdenum disilicide elements with unique right-angle bend and sidewall mounting reduce maintenance usually associated with element termination and mounting
• Designed for easy replacement without matching resistance values
• Fast heat-up and recovery with excellent uniformity and energy efficiency
• Increased resistance to thermal shock, ideal for rapid cycling over extended periods

Overtemperature Control (OTC)†

• Adjustable digital overtemperature control protects furnace and load in the event of primary control circuit failure
• Overrides main controller and shuts off power to furnace if high limit is reached
• Manual reset required for safety
• Operates via signal from independent thermocouple

Programmable Controller With Communications (COM Models)

• With RS-485 data port (communications card and port) for connection to remote computer
• Enables modification, interrogation and data transfer of instrument control and configuration parameters
• Up to 30 units can be connected to one PC
• Software not included (available as an option)

Digital Multiple Program, Multiple Segment Programmable Controller

• Microprocessor-based PID control (proportional, integral, derivative) prevents overshoot
• Multiple programs and segments for ramp (up and down) and dwell (timed hold) temperature control
• Simultaneous digital LED display of actual temperature vs. setpoint in either °C or °F

Digital Single-Setpoint Controller

• Microprocessor-based PID control (proportional, integral, derivative) prevents overshoot
• Single segment, single setpoint, one ramp to setpoint
• Adjustable high limit overtemperature protection
• Simultaneous LED display of actual temperature vs. setpoint in either °C or °F

• Composite research
• Precious and exotic metals treatment
• High-temperature ceramic research
• Powder metallurgy
