Kofloc 8500MM Mass Flow Controller driven by a 24 VDC power supply has been developed as a successor to the MODEL 8300.
Kofloc 8500MM Mass Flow Controller driven by a 24 VDC power supply has been developed as a successor to the MODEL 8300. The viewpoint change function of the display unit and the pattern setting function are unique to this model, and noise resistance has been improved dramatically. A sister model with a detachable display and setting unit is also available
