- RF4468N is highly intelligent, solved the problems which existed in the industry for so many years.
  a) Touchscreen operation, flow rate, specimen rack rotation speed, wipe rotation speed can be set in the touchscreen.
  b) Flow rate automatic control, no need manual adjusted.
  c) Pump control, the water tank pressure is stable.
  d) Precision test heads, provides accurate and even water drops.
  e) Water level automatic controlled in the water tank.
  f) Testing water internal recycling, saving a lot of water resources.
  g) Testing cup can be lifted individually, much more convenient for replacing specimens.
  h) An external temperature-controlled water supply device can be connected, to make the RF4468N can test specimens under different water temperatures.
- Beautiful appearance and convenient operation.
