Lindberg/Blue M LGO Box Furnace, 100 to 1200 deg C, 55.3 L Digital 25-Program, 500-Segment Programmable Controller, OTC Over Temperature Controller, FM Flowmeter, Horizontal Side Swing Door
Utilize the latest technical advances in heating elements, insulation and temperature control integrated into a self-contained cabinet with Thermo Scientific Lindberg/Blue M LGO Box Furnaces. Furnaces feature proprietary LGO (light gauge overbend) heating elements and Thermo Scientific Moldatherm insulation for efficient and economical transfer of heat to the chamber, with low exterior temperatures. Variable heat-up rate eliminates thermal shock to materials with inherently quick heat up and cool down rates.
- Feature exclusive LGO heating elements and Moldatherm insulation for efficient and economical transfer of heat to the chamber, with low exterior temperatures
- Variable heat-up rate eliminates thermal shock to materials with quick heat-up and cool-down rates
- Air vent (1 in. dia., top) and air inlet (0.375 in. dia., rear) for inert atmosphere exchange; (Note: door is not gas-tight)
- Self-tuning, digital instrumentation for precise temperature setpoint and display
- Platinel II thermocouple for longterm stability
- 0.6 cu.ft. models feature vertical lift door; 2 cu.ft. models feature horizontal side swing door, hot side facing away from the operator for protection
Microprocessor Control
- Microprocessor-based self-tuning PID control provides optimum thermal process, prevents overshoot
- Control panel designed for easy access and maintenance
- Main power ON/OFF switch on the control panel
- Adjustable high limit overtemperature protection
- Simultaneous LED display of actual temperature vs. setpoint in °C or °F
- Safety door switch interrupts power to the heating element when the door is opened; protects heating elements and minimizes exposure to end-user
- Removable shelves for versatility
- Moldatherm hearth plate supports the load and prevents damage due to spillage
Applications:
- Drying
- Ashing
- Annealing
- Enamelling
- Tempering
- Heat treatment

Digital Multiple-Program, Multiple-Segment Programmable Controller
- Multiple programs and segments for ramp (up and down) and dwell (timed hold) temperature 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
Overtemperature Control (OTC)
Adjustable digital overtemperature control, available on selected models with(B)suffix designation
- 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 magnetic contacts through the signal from the independent thermocouple
Flowmeter Option (FM) (Inert Atmosphere Only)
- Gas flowmeter, adjustable, located on the front control panel
- Adjustable flowrate, range 1.0 to 10.0 cu. ft./hr. standard
- Suitable for inert gas or airflow to chamber
- Allows fresh air exchange for ashing applications Not suitable for combustible or volatile gases
