Key Features

Choice of side hinge or vertical lift door
Air vent (1 in. dia., top) and air inlet (0.375 in. 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℃ or ℉
Safety door switch interrupts power to heating element when door is opened; protects heating elements and minimizes exposure to end-user
