Description

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 chamber, with low exterior temperatures. Variable heat-up rate eliminates thermal shock to materials with inherently quick heat up and cool down rates.

Key Features

• Choice of side hinge or vertical lift door
• Air vent (1 in. dia., top) and air inlet (0.375 in. dia., rear) for inert atmosphere exchange (may experience some leakage at door)
• Self-tuning, digital instrumentation for precise temperature setpoint and display
• Platinel II™ thermocouple for long-term stability
• 0.6 cu. ft. models feature vertical lift door; 2 cu. ft. models feature horizontal side swing door, hot side facing away from operator for protection

Microprocessor Control

• Microprocessor-based self-tuning PID control (proportional, integral, derivative) provides optimum thermal process, prevents overshoot
• Control panel designed for easy access and maintenance
• Main power ON/OFF switch on control panel
• Adjustable high-limit overtemperature protection
• Simultaneous LED display of actual temperature vs. setpoint
• Can be configured to display temperature in either °C or °F
• Safety door switch interrupts power to heating element when door is opened; protects heating elements and minimizes exposure to end-user
• Removable shelves for versatility
• Moldatherm™ hearthplate supports load and prevents damage due to spillage

Digital, Single-Setpoint Controller

• Single segment, single setpoint, one ramp to setpoint

Digital Single-Program, Multiple-Segment Programmable Controller

• Single program with multiple segments for ramp (up and down) and dwell (timed hold) temperature control

Digital Multiple-Program, Multiple-Segment Programmable Controller

Available on models with (P) suffix designation

• Multiple programs and segments for ramp (up and down) and dwell (timed hold) temperature control

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 signal from independent thermocouple

Flowmeter Option (FM) (Inert Atmosphere Only)

Available on selected models with (FM) designation

• Gas flowmeter, adjustable, located on 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

Ordering Information:

Required power cord and hardwiring not included. Optional RS485 Digital Communications Port 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.

†Specify Option

B for Overtemperature Control (OTC) when ordering.

Includes

One two-part shelf (0.6 cu. ft. models have one shelf position at center position; 2.0 cu. ft. models have three shelf positions)
