METROVAC – Laboratory for vacuum technology and metrology [NI-SERV-2020-40]
Metrovac is the National Reference Laboratory for Vacuum Metrology in Portugal, operating under ISO/IEC 17025 accreditation and ensuring traceability to international standards (BIPM, EURAMET).
Service/Expertise Overview
We provide calibration of vacuum gauges down to 1 × 10⁻⁶ mbar, including Pirani, capacitance diaphragm (CDG) and ionization gauges.
We also calibrate helium reference leaks with delivery to vacuum, and reference leaks for other gases with delivery to atmosphere.
In addition, Metrovac is accredited for testing refrigerant gas leak detectors.
Beyond our accredited scope, we develop tailored solutions for ultra-low gas-flow measurement, including membrane permeability and leak-tightness testing.
Metrovac also contributes to European R&D programmes (EMPIR, Horizon Europe), advancing vacuum metrology and ultra-low pressure standards.
Competitive advantages
Metrovac is the only laboratory in Portugal combining expertise in vacuum technology and metrology, with over 30 years of experience in the field.
Beyond calibration services, we design and prototype advanced instruments for vacuum and gas analysis, bridging metrology with industrial innovation.
For over three decades, Metrovac has been a trusted partner for industry, research, and metrology institutes, delivering precision, reliability, and innovation in vacuum technology.
Applications
Applicable to all vacuum-based processes, including thin-film deposition, hard coatings, lyophilization, vacuum drying, leak testing, cryogenics, space simulation, and research.
