• One or four stirring positions available.  
• Microprocessor control ensures accurate and stable setpoints for temperature and stirring speed  
• Electronic feedback controls monitor either top plate surface or liquid temperature (when using external PTFE-coated probe, included) and adjust to setpoint  
• Single control knob controls heat and speed; lock feature prevents accidental changes  
• Digital display for temperature or rpm  
• Powerful motor and magnetic system prevent magnetic decoupling  
• Stir Trac* breaking feature brings stir bar to an immediate stop for quick false removal and prevents runaway or decoupled stir bars  
• Temperature adjusts in 1° increments  
• Four user-defined temperature/speed memory keys recall settings  
• Calibration mode allows remote probe to be calibrated to external standards; probe can be programmed as a system (probe, control, display) at any user-selected temperature  
• Can be used in 0° to 27°C, 80% relative humidity, noncondensing environment  
• RS-232 port allows output of time count, temperature setpoint, top surface/remote probe temperature, stirring setpoint and actual speed  

Safety Features  

• Red HOT TOP warning light activates when heating surface is above 50°C (122°F); unit flashes HOT OFF until surface temperature falls to 50°C or below, even when heat control is turned off  
• Adjustable overprotection circuit limits top plate temperature, prevents runaway conditions  
• Rugged low-profile cast aluminum body provides stability and durability  
• Unit design protects internal components from accidental spills  
• Walk-away timer shuts off heating, stirring or both after preset user-defined interval  
• Includes: Detachable line cord and plug, 6 in. Type K probe. Stirring models also include stir bar  

Ceramic Top Models  

• Clean easily and resist alkalis and acids  
• Seamless, reflective white surface aids sample visibility  
• Heat to higher temperatures than aluminum tops   

Aluminum Top Models  

• Rugged and chip-resistant for superior durability  
• Allow uniform heat distribution across surface
