Series MR 3004 safety

Highest safety standards available

  • Only magnetic stirrer with 4 independent safety circuits
  • Unintentional changing of set point temperature is impossible
  • Safety control circuit by second independent Pt 100 in the hot plate
  • Adjustable safety margin at which the unit will cut-out in case of malfunction
  • Digital display for speed and temperature (both, set point and actual)
  • Guaranteed not overshooting of the selected set point temperature (protection of thermo-sensitive substances)
  • Electronically controlled speed, control accuracy ± 1%
  • Temperature control with microprocessor (fuzzy logic)
  • Hot plate residual heat indicator lights when unit is turned off
  • Connection for medium temperature sensor (please order separately as an accessory)
  • RS 232 interface and analog output
