Lindberg/Blue M 1700°C Box Furnaces
Thermo Scientific Lindberg/Blue M 1700°C furnaces are designed for efficient, high-temperature use with minimal maintenance. These furnaces feature fast heatup to high temperatures, unique door design and control sophistication ranging from solid-state, single setpoint to more versatile microprocessor-based systems with programming and communications options. Side swing door provides full and easy access to the chamber and protects the user from heat surge. Solid-state power module with ammeter, circuit breaker, transformer and front panel indicator lights for "Ready Element" and "Main Power Applied". Moldatherm® high-temperature ceramic fiber insulation with advanced graded design allows for fast heat-up and resistance to thermal shock. Moldatherm® hearthplate supports sample loads and protects the chamber from spills or mishandling. High-volume cooling fans move air between inner and outer chamber to reduce exterior shell temperatures and improve energy efficiency and enhance operator safety. Adjustable digital overtemperature control protects the furnace and load in the event of a primary control circuit failure. Long-life type "B" thermocouples with 10 ft. compensated lead wire and polarized plug for accurate high-temperature measurement. (Sample Photo Shown. Individual models may differ from the image shown.) Smart Heating Elements ■Molybdenum disilicide elements with unique right-angle bend and sidewall mounting reduce maintenance usually associated with element termination and mounting ■Designed for easy replacement without matching resistance values ■Fast heat-up and recovery with excellent uniformity and energy efficiency ■Increased resistance to thermal shock, ideal for rapid cycling over extended periods Overtemperature Control (OTC) ■Adjustable digital overtemperature control 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 signal from independent thermocouple ■Must specify Option B for OTC when ordering. Programmable Controller With Communications (COM Models) ■With RS-485 data port (communications card and port) for connection to remote computer ■Enables modification, interrogation and data transfer of instrument control and configuration parameters ■Up to 30 units can be connected to one PC ■Software not included (available as an option) Digital Multiple Program, Multiple Segment Programmable Controller ■Microprocessor-based PID control (proportional, integral, derivative) prevents overshoot ■Multiple programs and segments for ramp (up and down) and dwell (timed hold) temperature control ■Simultaneous digital LED display of actual temperature vs. setpoint in either °C or °F Digital Single-Setpoint Controller ■Microprocessor-based PID control (proportional, integral, derivative) prevents overshoot ■Single segment, single setpoint, one ramp to setpoint ■Adjustable high limit overtemperature protection ■Simultaneous LED display of actual temperature vs. setpoint in either °C or °F Ordering Alerts: Required power cord, hardwiring not included.
