How Much Does 647C Cost in 2026?

Used 647C units in 2026 range from $1,200 to $1,800, while refurbished units command $1,500 to $2,200.

Units with >40,000 RF-hours are typically available, but those with fewer hours may fetch lower prices. Note that 2026 pricing is volatile due to supply chain delays, so verify current market rates before finalizing a bid. Prices for 2026 units are also influenced by regional demand, with North America and Asia-Pacific markets showing the highest activity. Always confirm the exact RF-hour count and warranty status before purchasing.

647C Specifications and Compatible Tools

The 647C operates on 24V DC power, supports 100–1000 sccm flow rates, and features a 1000 Hz sampling rate for real-time control. It is compatible with AMAT Centura models (400, 450, 500 series; 2010–2018), Lam Research TCP (5000, 6000 series; 2012–2019), TEL E650 (300, 400 series; 2015–2020), and Novellus Concept II (500, 600 series; 2017–2022). Avoid units with part number 647C-001, as these are obsolete and incompatible with newer tool firmware. Always verify the tool’s model year to ensure compatibility with the 647C’s control protocols.

What to Check Before Buying a Used 647C in 2026

RF-hour count: Confirm the unit has >40,000 RF-hours to ensure operational reliability. Units with fewer hours may require calibration.
Voltage and current test: Use a multimeter to verify 24V DC output and 1.5A max current. Deviations indicate potential circuit board failure.
Flow calibration: Test with a mass flow meter (0.5% accuracy) to confirm flow rate precision across 100–1000 sccm. Rejected units show >2% deviation.
Firmware version: Check for updates from MKS Instruments (2025 or later). Older firmware may lack support for 2026 tool software.
Physical inspection: Look for corrosion on connectors or burnt circuit boards. Replace units with visible damage.
