Accredited Industrial Pressure Calibration Services
10 pressure calibration disciplines, each performed by accredited laboratories to recognized acceptance criteria, with NIST-traceable results documented for audit and compliance.
Calibration Disciplines
Pressure Gauge Calibration
Pressure gauges are verified against dead-weight piston references with measurement uncertainty traced back through NIST to the SI pascal, with as-found and as-left readings captured at ascending and descending test points.
View scope ↗ 02Digital Pressure Gauge Calibration
Digital pressure gauges receive multipoint comparison against a primary standard across the configured range, with display linearity, zero drift, and span repeatability documented on the certificate.
View scope ↗ 03Manometer Calibration
Liquid-column manometers are verified against a reference column under controlled temperature and fluid-density conditions; digital and inclined manometers receive multipoint comparison against an accredited reference.
View scope ↗ 04Pressure Transmitter, Transducer & Sensor Calibration
Transmitter and transducer calibration includes 4-20 mA loop verification across the configured span, with linearity, hysteresis, and repeatability captured at ascending and descending test points.
View scope ↗ 05Pressure Switch & Relief Valve Calibration
Pressure switches are verified at set-point and reset-point with hysteresis recorded; relief and safety valves are bench-tested for cracking pressure, reseat pressure, and full-flow capacity.
View scope ↗ 06Leak Tester Calibration
Leak testers are verified using calibrated reference leaks across the expected detection range, and pressure-decay instruments receive internal volume verification under controlled temperature conditions.
View scope ↗ 07Piston Gauge Calibration
Piston gauge certification follows cross-float comparison against a primary standard, with piston-cylinder effective area, mass loadings, and ambient corrections documented on the ISO/IEC 17025 certificate.
View scope ↗ 08Deadweight Tester Calibration
Deadweight tester certification is performed by cross-float against a primary standard, with mass set tolerances, gravity correction, and ambient air-buoyancy compensation recorded for each test point.
View scope ↗ 09Differential Pressure & Magnehelic Gauge Calibration
Differential pressure and Magnehelic gauges are verified at both static line pressures and across the differential span, with zero stability, linearity, and full-scale accuracy captured on the certificate.
View scope ↗ 10Vacuum Gauge Calibration
Vacuum gauge verification uses a calibrated reference gauge across the working range, with ionization-type and capacitance-manometer instruments receiving the additional outgassing and zero-stability checks their construction requires.
