The Model DF-350 Series is a digital mass flow controller with an integral indicator that operates on a 24-V power supply. It offers features equivalent to the DF-250 Series designed for up to 50 SLM.

Features

  • High accuracy (±1% S.P.), fast response (≤ 1 sec in all ranges)
  • Support of multiple ranges and multiple gases
  • Communication functions installed as a standard feature (RS485)
  • RoHS CE standard compliant
  • Driven by a single 24 V DC supply voltage
  • With or without indicator (selectable)
  • Selectable Input/output signal
