Thermolyne™ Largest Tabletop Muffle Furnaces
Experience unparalleled performance in materials heat treatment with the Thermolyne™ Largest Tabletop Muffle Furnaces. Designed for precision and durability, these furnaces are ideal for a variety of applications including annealing glass, determinations of volatiles, catalyst research, and ashing both organic and inorganic samples.
Outstanding Features
- Advanced LED digital-set/digital-display temperature controller with microprocessor control for enhanced usability.
- The LED display provides a dual readout of both setpoint and actual furnace temperatures in Celsius (°C) or Fahrenheit (°F).
- Customizable overtemperature protection to ensure safe operation.
- Open thermocouple protection prevents damage to the furnace.
- Power output is adjustable from 1 to 100% for versatile heating management.
Safety and Design Features
- Heating elements are strategically positioned on the top, bottom, and sides to deliver superior temperature uniformity.
- Built-in vent port effectively removes undesirable contaminants and moisture, prolonging the lifespan of both the elements and the unit.
- Chamber rear features a 0.95 cm (0.38 in.) diameter port for external temperature monitoring with independent devices.
- Critical components and heating elements are safeguarded by a 35A circuit breaker for enhanced safety.
- The door safety switch immediately cuts power to the heating elements when the door is opened, ensuring user protection.
Choice of Temperature Controllers
- The furnaces equipped with B1, C1, or D1 control options utilize a mechanical Overtemperature Protection relay.
- B1: Features digital single setpoint control with one ramp to setpoint and dwell; displays actual temperature or setpoint on a single readout.
- C1: Digital programmable control supporting one stored program with 8 segments for varied heating profiles.
- D1: Advanced programmable control allowing up to 4 stored programs, each with 16 segments; includes RS-232 communications interface for connectivity.
