Product Details

Thermo Scientific LGO Series Box Furnaces feature the latest technical advances in heating elements, insulation and temperature control, all integrated into a self-contained cabinet. Furnaces feature patented LGO (light gauge overbend) heating elements and Moldatherm insulation for efficient and economical transfer of heat to the chamber, with low exterior temperatures.

Includes the C2 Controller

Programmable with one (1) stored program of sixteen (16) segments. Each segment includes one ramp and one dwell, so you can program 16 ramp/dwell cycles.

The ramp is used to vary the heat-up rate to your specified setpoint. The furnace will then dwell (hold the temperature) at a set level for a specified time.

An LED display simultaneously shows both setpoint and actual furnace temperatures.

Super Control (Fuzzy logic) suppresses overshooting of temperature

Customer initiated auto-tune function will adjust and update the PID parameters to the optimum settings for new temperature setpoints

Selectable self-tuning PID control (proportional, integral, derivative) provides optimum thermal process and prevents overshoot

Control panel designed for easy access and maintenance

Main power ON/OFF switch on control panel

Adjustable high-limit overtemperature protection

Can be configured to display temperature in either °C or °F

Variable heat-up rate eliminates thermal shock to materials with quick heat-up and cool-down rates

Side-hinge door for convenient operation and full chamber access

Air vent (1in. dia., top) and air inlet (1/4-inch Male Pipe Thread, rear) for inert atmosphere exchange; will experience some leakage at door

Self-tuning, digital instrumentation for precise temperature setpoint and display

Platinel II thermocouple for long-term stability

Safety door switch to interrupt power to heating element when door is opened; protects heating element and minimizes exposure to end-user

Three shelf positions; 1 two-part shelf included with furnace

Moldatherm hearthplate supports load and prevents damage due to spillage

NOTE: Furnace must be hard wired

Adjustable digital overtemperature control (OTC)

OTC - Protects furnace and load in the event of primary control circuit failure

OTC - Overrides main controller and shuts off power to furnace if high limit is reached

OTC - Manual reset required for safety

OTC - Operates via magnetic contacts through signal from independent thermocouple
