The BLUE M STABIL-THERM ELECTRIC OVEN SOLID STATE CONTROLLER delivers precise temperature regulation using solid-state electronics and PID control logic for laboratory and industrial thermal processes. Type J thermocouple measurement combined with proportional power distribution to electric heaters ensures stable heating across diverse applications. Independent overtemperature protection with manual reset and audible alarm safeguards against thermal excursions, while an integrated timer function enables programmed countdowns or continuous operation.
Technical Specifications
Control & Measurement
• Solid-state controller architecture with proportional integral derivative (PID) control logic
• Type J thermocouple temperature measurement
• Setpoint resolution: ±1°C
• Temperature uniformity: ±1°C achievable with proper insulation and airflow management
• Power proportioning via solid-state relays to electric heaters
Safety & Protection
• Independent overtemperature alarm (OTA) or FM-approved independent over-temperature protection system
• Heater and motor power disconnection on OTP activation
• Audible buzzer alarm requiring manual reset
• High limit set approximately 10°C (20°F) above maximum rated oven temperature
Thermal Management
• Fiberglass insulation: minimum 2 inches on all six sides
• Double-wall insulated door to minimize heat loss
• Heating rate decreases as chamber approaches setpoint due to PID control
• Minimum heating applied during cooling to prevent undershoot
Construction
• Interior: Stainless steel
• Exterior: Stainless steel or enameled steel with baked-on powder-coated enamel finish
• Adjustable stainless steel wire shelves (or nickel-plated steel for enameled models)
• Shelf design maximizes internal airflow
– Key Features
• Timer function with automatic shutdown at completion; continuous operation via locked timer knob
• LED or LCD display options for setpoint and process variable monitoring
• Optional access ports with stoppers for external sensor probe introduction
• Lead-in ports available (3″ O.D., 2 1/8″ I.D.) for external connections
• Optional RS-232, Ethernet, and GPIB connectivity for advanced controller variants
– Typical Applications
Laboratory thermal processing, industrial heat treatment, environmental testing, and controlled heating operations requiring stability within ±1°C.
– Compatibility & Integration
Advanced controller options such as Watlow F4T enable remote control, monitoring, chart printing, email alerts, and cloud data storage capabilities.
