At International Process Solutions (IPS), ultra‑low vacuum calibration—also known as UHV calibration—ensures exceptional performance and reliability for critical gauges and sensors measuring pressures from 10⁻³ Torr down to 10⁻¹² Torr.

Core Capabilities:

• Calibration of Bayard‑Alpert ionization, hot/cold cathode, capacitance manometers, spinning rotor gauges, residual gas analyzers, and thermocouple gauges.
• Utilization of primary standards traceable to NIST and intrinsic standards via ISO‑compliant methods (ISO 3567, ISO/TS 27865).
• Operation of UHV stainless-steel chambers equipped with cryopumps, turbomolecular pumps, ion pumps, and bake‑out capabilities to reach pressures below 10⁻¹⁰ Torr .

⚙️ Comprehensive Calibration Services & Labs

IPS operates multiple ISO 17025‑accredited labs across California:

IPS also provides special calibration services, including ultra‑low vacuum generation & measurement and optical standards (e.g. UV spectroscopy) support.

✅ Accredited Standards & Quality Assurance

• ISO/IEC 17025 accreditation across electrical, thermodynamic, dimensional, and time/frequency parameters.
• Calibration documentation includes as-found/as-left data, measurement uncertainty, and full traceability to national standards.
• Calibration often performed in controlled cleanroom environments with baked chambers and real-time data acquisition .
