How Much Does Granville-Phillips 370 Stabil-Ion Gauge Cost in 2026?

Used units typically range from $450 to $2,200 in 2026, with refurbished models at $1,800–$2,500. New OEM replacements exceed $10,000, offering 70–85% savings over original equipment. Caveat: Units with >10,000 operational hours require filament resistance testing (spec: 5–8 Ω) to avoid premature failure. Market pricing correlates with vacuum integrity test results (leak rates <1×10⁻⁹ Torr·L/s acceptable).

Granville-Phillips 370 Stabil-Ion Gauge Specifications and Compatible Tools

Operates at 2 kV DC, measures 10⁻³ to 10⁻⁷ Torr, and consumes 15 W. Key spec: filament lifespan >8,000 hours at 90% duty cycle. Compatible with:

Applied Materials 5500 CVD (2000–2010 production)
Lam Research Centura P5000 (1998–2005)
Veeco Nexus 300 (2002–2008)
Exclusion: Not compatible with Varian 3000 Series (part # 300-0452) due to conflicting filament geometry. Verify tool’s ion gauge socket dimensions (spec: 25.4 mm OD).

What to Check Before Buying a Used Granville-Phillips 370 Stabil-Ion Gauge

Filament integrity: Measure cold resistance with a multimeter (spec: 5–8 Ω; >10 Ω = reject).
Vacuum leak test: Use a helium mass spectrometer; leak rate must be <5×10⁻¹⁰ Torr·L/s.
Signal stability: Connect to an oscilloscope; output noise >±5% of reading = failure.
Age verification: Units >15 years old require full rebuild (filament, insulators, seals).
Calibration logs: NIST-traceable certification post-2020 preferred; absence adds $300–$500 recertification cost.

FAQ

Q: Used vs. refurbished Granville-Phillips 370—what’s the difference?
A: Used parts are operational-as-is; refurbished includes replaced filament, insulators, and vacuum seals.

Q: How to test accuracy without a vacuum chamber?
A: Use a known-reference leak (e.g., 1×10⁻⁶ Torr) and compare output to spec sheet.

Q: Compatible with modern ALD tools?
A: Yes, if the tool accepts 2 kV DC and has a 2
