How Much Does a Used MKS 630 Heated Baratron Manometer Cost in 2026?

Used units range from $728–$1,450, while refurbished models (with recalibration and heater replacement) cost $1,890–$3,560. This represents 94–97% savings vs. new (MSRP: ~$12,000). Caveat: Units older than 15 years (pre-2011) depreciate 30–40% further due to heater coil fatigue. Always verify calibration certificates post-2020 for traceability to NIST standards.

MKS 630 Heated Baratron Manometer Specifications and Compatible Tools

Pressure Range: 1 × 10⁻⁵ Torr to 1 Torr
Power Consumption: 15W (heater: 12W, sensor: 3W)
Voltage: 24V DC (±5%)
Output Signal: 4–20mA (loop-powered)
Frequency Response: 0.1 Hz–1 kHz

Compatible tools:

Applied Materials Centura (1998–2005)
Lam Research Endace 5500 (2001–2007)
ASMI Fusion F12 (2003–2009)

Warning: Not compatible with Veeco Nexus 300 (P/N 712-000123) due to mismatched signal conditioning circuitry.

What to Check Before Buying a Used MKS 630 Heated Baratron Manometer in 2026

Calibration Drift: Use a dry film reference standard (e.g., MKS 937A) to confirm ±5% accuracy at 1 × 10⁻³ Torr; >7% error requires sensor replacement.
Heater Coil Resistance: Measure with a multimeter (ohmmeter mode); 22–28Ω is nominal. >35Ω indicates coil degradation.
Insulation Resistance: Test with a megohmmeter (500V DC); >100MΩ between heater and sensor ground. <50MΩ = short risk.
Service History: Reject units with >10 years of continuous operation without a full heater rebuild (MKS SR-630-2023).
Process Gas Compatibility: Verify exposure history to HF or NH₃; these corrode the ceramic diaphragm (replacement cost: $2,100).

FAQ

Q: Does the MKS 630 require a separate power supply?
A: No. It’s loop-powered via the 4–20mA signal, but the heater requires a dedicated 24V DC source.
