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.
  • Not available in Europe.

Features

  • Choice of side hinge or vertical lift door.
  • Air vent (1" dia., top) and air inlet (0.375" 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).
