5850IA1BL3Y2BAA is a configured Brooks Instrument 5850i thermal mass flow controller identifier. Official Brooks 5850i documentation supports the model-level identity as a gas mass flow controller with a flow sensor, control valve, integral electronics, analog command input, and analog output options; exact gas, full-scale range, valve state, fitting, and calibration details remain configured-unit attributes that should be verified from the physical nameplate
Configurations vary. Verify the exact unit before choosing a replacement.
