Operating Features       

• 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       * Thermo Scientific™ 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       * Ceramic tops clean easily, resist chemicals and provide fast boiling time       * 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
