Brooks Instrument Model 4860 Mass Flow Meter

About this part

4860ABC2B1A1A3B10A is a configured Brooks Instrument model 4860 gas mass flow meter from the legacy 4800 Series. The 4860 measures thermal mass flow and provides analog output with an RS-232 interface; unlike the companion 4850, it is a meter rather than a flow controller. Gas, full-scale range, fittings, power and output selection remain configuration-specific and must match the unit label and calibration record

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