How Much Does MKS 627D/628D Baratron Capacitance Manometer Cost in 2026?

Used units range from $728–$1,200, while refurbished models (with recalibration and seal replacement) cost $1,800–$3,560. New OEM units exceed $12,000, offering ~75–90% savings with used/refurbished options. Caveat: Units with >10 years of lifecycle (pre-2016 installs) require vacuum decay testing (per MKS 627D-TP-09 protocol) to confirm diaphragm integrity. Avoid parts with >50,000 pressure cycles without recent capacitance recalibration.

MKS 627D/628D Specifications and Compatible Tools

Operates 0.0001–1000 Torr, ±0.5% accuracy, 12–36V DC power, 1–10 kHz frequency response. Compatible with:

Applied Materials Centura (1998–2005, model 8920-64232)
Lam Research Endura (2000–2007, model 9580-4112A)
Tokyo Electron Lambda Flex (2002–2009, model TE-7324-12)
Exclusion: Not compatible with Varian 300mm PECVD (part 628D-Mod3) due to differential pressure offset errors. Verify tool’s vacuum controller firmware version (v3.2+ required for 627D).

What to Check Before Buying a Used MKS 627D/628D in 2026

Diaphragm wear: Use a laser interferometer to measure flatness; reject if deviation >2µm (spec per MKS 627D-Eng-04).
Electrical continuity: Measure coil resistance with a multimeter; 1.2–1.5Ω for 627D, 1.0–1.3Ω for 628D.
Calibration logs: Demand NIST-traceable certs from 2021 onward; recalibrate if >5 years old.
Port erosion: Inspect ¼” Conflat flanges for >50µm wear using a micrometer.
Cycle count: Query PLC logs for pressure cycles; >80,000 cycles correlates with 30% failure risk (MKS 2023 field data).
