5861IA112H2DEA is a configured Brooks Instrument 5861i mass flowmeter identifier. Official Brooks documentation identifies the Model 5861i as a mass flowmeter for accurately measuring gas flow, with standard nitrogen-equivalent ranges from 10 slpm to 100 slpm and 15 to 28 Vdc power. Stored Sonisys auction records and surplus/calibration pages associate this exact identifier with 100 SLM and 15-28 Vdc context; those observed details should be confirmed from the unit label and calibration records before reuse
Unit-specific configuration
Observed configuration
Historical listing records identify this part as 100 SLM. Exact gas, range, fittings, valve configuration, and communication interface must be verified from the physical unit label.
Configurations vary. Verify the exact unit before choosing a replacement.
