How Much Does FCS-4001-02F Cost in 2026?

In 2026, used FCS-4001-02F units typically range from $1,200–$1,800, depending on operational hours and calibration history. Refurbished units with verified <20,000 hours and full documentation average $2,500–$3,000. New OEM pricing remains undisclosed but exceeds $7,000, offering 50–70% savings for used/refurbished options. Units with >40,000 RF-hours often exhibit degraded flow accuracy and require recalibration, reducing value by 20–30%. Market demand remains stable due to TEL E612 tool prevalence in 2026, but pricing volatility increases for units lacking NIST-traceable calibration certificates. Prioritize units with <15,000 hours and recent leak tests for minimal risk.

FCS-4001-02F Specifications and Compatible Tools

The FCS-4001-02F is a Fujikin mass flow controller rated for 200 sccm argon at 12–24V DC, with ±2% accuracy and <1.5 seconds response time. It operates at 0–5V analog input and features a brass body with PTFE seals. Compatible tools include TEL E612 (2010–2015), Hitachi M-6410 (2008–2012), and ULVAC SPUT-1000 (2005–2010). Warning: Do not substitute with FCS-4001-01F (200 sccm N₂), as gas-specific orifice design causes ±5% flow deviation in argon applications. Cross-check tool manuals for Fujikin part number FCS-4001-02F in the MFC section to confirm compatibility.

What to Check Before Buying a Used FCS-4001-02F in 2026

Visual corrosion: Reject units with pitting on the brass body or discolored PTFE seals; use a 10x loupe to inspect internal valve surfaces.
Electrical continuity: Test with a multimeter for open circuits in the 4–20mA output loop; >10Ω resistance indicates wiring degradation.
Flow bench verification: Confirm ±2% accuracy at 100 sccm and 200 sccm using a certified mass flow bench; >3% deviation requires recalibration.
Diaphragm wear: Measure diaphragm
