MF50S/AC1DA1ID0KA1B1
Brooks Smart Mass Flow Controller
About this part
MF50S/AC1DA1ID0KA1B1 is a configured Brooks Instrument MF50S Smart Mass Flow controller. The MF50S belongs to the Brooks MF Series Smart Mass Flow controller family, a weatherproof IP65 / NEMA 4X elastomer-sealed thermal mass flow platform based on Brooks 5850S-5864S Smart Mass Flow products. Sonisys auction history shows this configured identifier in 3/8 inch N2 units with 3 SLPM and 12 SLPM observed ranges; those values describe stored configured-unit examples, not every MF50S/AC1DA1ID0KA1B1 unit
Configurations vary. Verify the exact unit before choosing a replacement.
