How Much Does a Used Nitrogen (N2) Mass Flow Controller Cost in 2026?

In 2026, used N2 mass flow controllers (MFCs) with part numbers like MKS 1179B or Brooks 5850 range from $632–$3,320, depending on flow capacity and calibration history. Refurbished units with traceable certifications add $800–$1,200 to the base price. This represents 87–93% savings versus new equivalents (priced at $5,000–$10,000). Note: Controllers with flow ranges above 100 sccm (standard in 2018+ tools) command the higher end of the spectrum. Caveat: Units over 10 years old without recent rebuilds may require additional diagnostics, adding 15–20% to the purchase cost.

N2 Mass Flow Controller Specifications and Compatible Tools

Key specs: flow range 0–100 sccm, accuracy ±1% FS, response time <500 ms, operating voltage 5–24 VDC, and output signal 4–20 mA. Compatible tools include:

MKS 1179B (2005–2012, 0–100 sccm)
Brooks 5850 (2008–2015, 0–50 sccm)
Horiba FMA-30 (2010–2017, 0–200 sccm)
Exclusion warning: Do not install on MKS 267A systems, which require a 0–10 V analog output (N2 MFCs typically use 4–20 mA). Verify tool’s signal interface before purchase.

What to Check Before Buying a Used N2 Mass Flow Controller in 2026

Calibration validity: Ensure the last certification was within 12 months; older units may need recalibration at $150–$300.
Flow accuracy test: Use a calibrated gas bench to verify ±1.5% deviation at 50% of rated flow; reject if >±2%.
O-ring integrity: Inspect for cracks or hardening (use a 5× loupe); replace if >10 years old.
Response time: Trigger a step-change in flow with a digital multimeter (DMM); accept if stabilization occurs within 600 ms.
Voltage tolerance: Measure internal regulator with a DMM under load; must maintain
