Advanced engineering and specialized construction techniques include variable density insulation, double shell cabinets, long-life heating elements and vertical, horizontal side swing or swing down doors.
Microprocessor-based Control
- Selectable self-tuning feature sets best control parameters for the thermal process
- PID control (proportional, integral, derivative) prevents overshoot
- Main power ON/OFF switch on control panel
- Controlled heat-up rate eliminates thermal shock to materials
- Quick heat-up and cool-down rates
- Adjustable high-limit overtemperature protection
- Simultaneous LED display of actual temperature vs. setpoint
- Can be configured to display temperature in either °C or °F
Construction
- Unique double wall minimizes exterior surface temperatures for operator safety and energy efficiency
- Side-hinge door for convenient operation and full chamber access
- Long-life Type K thermocouple
- Air vent (1in. dia., top) and air inlet (0.375in. dia., rear) for inert atmosphere exchange; will experience some leakage at door
- Removable and replaceable Moldatherm hearth plate supports load and prevents damage due to spillage
- Energy-efficient Moldatherm insulation with embedded heating elements
- Safety door switch to interrupt power to heating element when door is opened; protects heating element and minimizes exposure to end-user
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
Ordering Information:
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.
Includes:
10ft. power cord except 1.5 cu. ft. models which require customer-supplied power cord or hardwiring.
Minimize outer surface temperatures while maintaining uniform heat distribution within the chamber. Thermo Scientific™ Lindberg/Blue M Box Furnaces include unique insulation and heating element composites, and are available in several popular chamber sizes to meet the most demanding laboratory applications.
