How Much Does a Used MKS 627 Baratron Capacitance Manometer Cost in 2026?

In 2026, used MKS 627 units range from $728–$2,500 for working but untested models, and $1,200–$3,560 for fully calibrated, NIST-traceable refurbished units. Refurbished parts save 29–75% compared to new pricing (typically $5,000–$8,500). Units with original calibration certificates (post-2020) command a 15–20% premium. Critical caveat: models manufactured before 2012 often exhibit ±1.2% drift due to degraded diaphragm materials, reducing effective lifespan by 30%.

MKS 627 Specifications and Compatible Tools

The MKS 627 operates across 1×10⁻⁵ to 1,000 Torr, with ±0.5% accuracy at 1–100 Torr (±1% below 1×10⁻³ Torr). It requires 24V DC and outputs 4–20mA or 0–5V signals. Compatible tools include:

Applied Materials Centura (1998–2005)
Lam Research Endura P5i (2000–2008)
SEMI E3 vacuum chambers (2002–2010)
Warning: Do not install on Veeco Nexus 300 systems (1999–2004) without a signal conditioner (part #VC-300-SC); the 0–5V output conflicts with the host’s 4–20mA requirement.

What to Check Before Buying a Used MKS 627 Baratron Capacitance Manometer in 2026

Calibration date: Reject units calibrated before 2021; drift exceeds ±1.5% beyond 5-year lifecycle.
Diaphragm integrity: Use a multimeter to measure baseline resistance (should read >10MΩ). <5MΩ indicates contamination.
Signal stability: Connect to a DAQ system; apply 100 Torr and log output for 10 minutes. Deviation >±2% invalidates accuracy.
Physical damage: Inspect the ceramic body for hairline cracks (use a 10x loupe); even minor fractures cause vacuum leaks.
Firmware version: Units with firmware pre-v3.2 (2015) lack modern compensation algorithms, reducing usable range by 40%.

FAQ

Q: Is a used MKS 627 better than a refurbished one?
A: Refurbished units include recalibration, replaced seals, and updated firmware. Used parts may require $300–$600 in service to meet spec
