• Built-in adjustable high limit overtemperature protection
• Simultaneous LED display of actual and setpoint temperatures in either °C or °F
• Silicon carbide heating elements for long-life, safety, and reliable service with maximum energy savings
• Safety door switch interrupts power to heating elements when the door is opened; protects elements and minimizes exposure to the operator
• Moldatherm hearth plate supports a load and protects the interior from spillage and mishandling

Thermo Scientific Lindberg/Blue M Multipurpose 1500°C Box Furnaces have a double-wall construction with Moldatherm insulation for rapid heat-up and cooldown, energy efficiency, and cooler exterior surface temperatures.

• Built-in adjustable high limit overtemperature protection
• Simultaneous LED display of actual and setpoint temperatures in either °C or °F
• Silicon carbide heating elements for long-life, safety, and reliable service with maximum energy savings
• Safety door switch interrupts power to heating elements when the door is opened; protects elements and minimizes exposure to the operator
• Moldatherm hearth plate supports a load and protects the interior from spillage and mishandling
• Type “R” thermocouple is integrated into chamber back wall
• Double-wall construction with Moldatherm insulation for rapid heat-up and cooldown, energy efficiency, and cooler exterior surface temperatures
• Adjustable high-limit overtemperature protection
• Microprocessor-based PID control
• 6L models with vertical lift door

C: Digital multiple-program, multiple-segment programmable control

• Up to 25 programs and up to 500 segments for ramp (up and down) and dwell (timed hold) temperature control per program
• Capability to repeat program steps, and cycles to repeat the whole program up to 999 times
• Program patterns can be based on either time or rate
• Large 5-digit LED display of actual temperature
• LCD display provides trend recording function, graphic prompts, configurable display data
• RS485 digital communications port available as an option on select models (add “COM” to the model number before the last letter, as shown in a note under spec table)
• Over-temperature control (OTC):
• Adjustable digital over-temperature 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 re-set required for safety
• Operates via magnetic contacts through a signal from the independent thermocouple

Applications
