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
