  • Filter and air stream monitoring for easier maintenance
  • Event memory for up to 12,000 events
  • For use with an extraction tube with a total length of max. 80m (2 x 50 m)
  • Automatic learning function for determining optimum sensitivity level (the units remain operative during this learning phase)
  • Adjustments can be made by means of a PC in combination with VConfig PRO and ASPIRE Windows software and a standard interface cable w/o interface (modules are not supplied as standard)
