How Much Does MKS 122AA-01000AB Cost in 2026?

Used units range from $2,500–$4,000 in 2026, depending on calibration history and exposure to corrosive gases. Refurbished models (certified by MKS or Tier 1 partners) cost $5,000–$6,500, saving 40–60% vs new ($12,000–$15,000). Caveat: Parts with >500 hours of NF₃ or Cl₂ exposure (common in etch tools) require full recalibration, adding $800–$1,200 to the cost. Always verify the last calibration date—MKS specs mandate recalibration every 3 years or 8,000 operating hours.
