  • lockable transparent door for protection of settings
  • alarm signals are given if the set limits are exceeded and a potential-free contact operates to e.g. auto-stop your machine to avoid quality problems
  • independent of pressure fluctuations in the gas supply
  • independent of packing speeds (MAP)
  • independent of package sizes (MAP)

Maximum Hygiene:
