Brooks Instrument 4850 Mass Flow Controller

About this part

4850ABB2B1B1K1C00A is a configured Brooks Instrument Model 4850 thermal mass flow controller identifier. Brooks ordering literature decodes the verified prefix and option positions as a revision-B controller with RS-232 plus 0-5 Vdc analog input/output, 24 Vdc power, 1/4-inch tube compression connections with filters, a 316 stainless-steel body with Viton seals and a normally closed valve, standard-location classification, and a 0.049-inch valve orifice. exact-part listings disagree on the calibrated gas and full-scale range, so those unit-specific values must be confirmed from the instrument label and calibration data sheet

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