Brooks Instrument Mass Flow Controller

About this part

4850ABB2B1B1JXC00A is a configured Brooks Instrument 4850 Series elastomer-sealed thermal mass flow controller for gas service. Brooks' official 4800 Series model-code table identifies this configuration with RS-232 and 0-5 Vdc analog input/output, 24 Vdc power, 1/4-inch tube-compression connections with filters, a normally closed valve, and standard safe-area classification. Gas, calibrated full-scale flow, inlet pressure, and outlet pressure remain unit-specific calibration details; listing evidence observes one AIR-calibrated 5 slpm unit but does not establish those values for every unit bearing the identifier

Configurations vary. Verify the exact unit before choosing a replacement.
