How Much Does a Used Granville-Phillips Ion Gauge Controller Cost in 2026?

Used units (tested, <5 years in service) range from $1,800 to $3,500 in 2026, depending on calibration history and connector condition. Refurbished models with OEM firmware updates cost $2,200 to $4,000. This represents ~60% savings vs new (MKS lists new units at $4,500–$7,000). Caveat: Controllers with >10k pressure cycles (trackable via internal log counters) may require vacuum chamber requalification, adding $500–$800 in labor. Always request a recent leak-test certificate (max 1×10⁻¹¹ Torr) before purchase.

Granville-Phillips Ion Gauge Controller Specifications and Compatible Tools

Key specs: 0–20 mA output, 24 VDC power supply, 10 Hz–1 kHz signal frequency, and ±5% accuracy (±2% with recalibration). Compatible with:

AMAT Centura Cluster Tool (1998–2003)
LAM Research P5000 Etcher (2001–2006)
Varian 3100 Turbo Pump Systems (1999–2004)
Exclusion: Not compatible with MKS 631B controllers (firmware conflict; check part #370-0124A). Verify tool’s ion gauge model (GP 354 vs 370) for signal protocol alignment.

What to Check Before Buying a Used Granville-Phillips Ion Gauge Controller in 2026

Voltage stability: Use a multimeter to confirm 24 VDC ±0.5 V under load; >25 V indicates regulator drift.
Signal noise: Connect to a signal generator; >1% RMS noise at 1 kHz invalidates accuracy.
Calibration drift: Compare against a NIST-traceable standard; >5% deviation requires full recalibration.
Connector wear: Reject units with pin creep >0.002” (measure with a micrometer).
Service history: Units >12 years old must have capacitors replaced (electrolytic capacitors degrade after 10k hrs).

FAQ

Q: Can I use a GP 354 controller with a modern Lam P7000 tool?
A: No. The P7000 requires a digital interface (MKS 635B); GP 354 is analog-only.

Q: Used vs refurbished — which is better?
A: Refurbished includes firmware updates and recalibration; used may save $300–$500 but requires pre-purchase testing.
