  Open Control + Multicontrol + Real-Time Control.
  Specialized Control Software based on LabVIEW.
  National Instruments Data Acquisition board (250 KS/s, kilo samples per second).
  Calibration exercises, which are included, teach the user how to calibrate a sensor and the
  importance of checking the accuracy of the sensors before taking measurements.
  Projector and/or electronic whiteboard compatibility allows the unit to be explained and
  demonstrated to an entire class at one time.
  Capable of doing applied research, real industrial simulation, training courses, etc.
  Remote operation and control by the user, as well as remote support from technical
  support, are always included.
  Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).
  Designed and manufactured under several quality standards.
  Optional ICAI software to create, edit and carry out practical exercises, tests, exams,
  calculations, etc. Apart from monitoring user's knowledge and progress reached.
  This unit has been designed for future expansion and integration. A common expansion is
  the Scada-Net (ESN) System which enables multiple students to simultaneously
  operate many units in a network.
