MKS GM50A Mass Flow Controller (MFC) Digitally-Controlled, O₂ Configured, Range of 0.4 to 20 sccm Full Scale, RS - 485, N.C Teflon Valve,4 VCR Male. PN: GM50A015201R5M020

The MKS GM50A Mass Flow Controller is configured to control O₂ or equivalent, having a Full-Scale Flow Range of 20 sccm and a control range of 0.4 to 20 sccm. It has a RS - 485 serial communication port, a 0-5 VDC or or 4 to 20 mA flow input/output signal and a Swagelok® 4 VCR® male input and output fittings. Typical response times are on the order of 500 milliseconds. Digital calibration yields 1% of set point accuracy on the calibration gas.

The multi-range capabilities can be configured through a web browser based application accessed by plugging the MFC into a router or a computer via Ethernet cable. The E-diagnostics application allows a user to monitor the MFC’s performance in real time as well as plot data and select variables.
