Used Helium Leak Detector

How Much Does a Used Helium Leak Detector Cost in 2026?

Used units from Agilent (model 59200A) or Edwards (model RGA300) range from $6,790–$20,550 in 2026, depending on sensitivity calibration and pump integration. Refurbished models with <5,000 operational hours add $3,200–$5,800 to the base price. This represents 85–90% savings versus new detectors (priced ~$45,000–$60,000). Caveat: Units with >8,000 cumulative hours often show >20% degradation in leak detection sensitivity (per 2025 SEMI standards). Always verify mass spectrometer tube condition—cracks or contamination void warranties and reduce accuracy by 30–50%.

Helium Leak Detector Specifications and Compatible Tools

Key specs: sensitivity 1×10⁻¹⁰ mbar·L/s, mass flow rate ≤50 sccm, operating voltage 20–30 kV DC, and frequency 2–5 MHz. Compatible with:

• Applied Materials Centura (2012–2017)
• Lam Research Endra ETch (2014–2018)
• AMAT P5000 CVD systems (2010–2016)
  Exclusion: Not compatible with Veeco Nexus 300 due to differing interface port configurations (part #VEE-PORT-300A). Verify ionization chamber dimensions—older Agilent models require 48.3 mm bore diameter, while Edwards units use 52.7 mm. Cross-check vacuum pump CF32 flange compatibility before purchase.

What to Check Before Buying a Used Helium Leak Detector in 2026

1. Pump hours: Reject units with >8,000 hours (per 2025 industry lifecycle data).
2. Sensitivity test: Use a 1×10⁻⁶ mbar·L/s leak standard; deviation >15% invalidates calibration.
3. Mass spectrometer tube: Inspect via UV light for cracks or carbon buildup (use a helium mass spectrometer for background gas checks).
4. Voltage stability: Measure with a digital multimeter—fluctuations >±5% at 25 kV indicate power supply wear.
5. Interface ports: Confirm CF32 flange and 24V DC input match your tool’s specs (Edwards models often require adapter #EDW-ADP-2024).
