Target group and benefits

Support quality, calibration and engineering teams with DANAK-accredited force, pressure and vacuum calibration with stated measurement uncertainty and traceability.

Traceable calibration for critical measurements
Our Force and Pressure Laboratory supports quality managers, metrology specialists, production engineers, and technical asset owners who rely on accurate force, pressure, and vacuum measurements for testing, manufacturing, and operational control. The facility provides DANAK-accredited calibration within defined force, pressure and vacuum ranges, with stated measurement uncertainty and traceability to international primary standards. This enables organisations to document the calibration status of force transducers, dynamometers, jacks, pressure gauges and vacuum instruments used in testing and production.

Accredited calibration with traceable measurement results
Calibration certificates provide documented measurement results with stated uncertainty and traceability to international primary standards. When instruments are used for acceptance testing, safety verification or performance validation, accredited calibration certificates provide the documented basis for confirming that readings remain within specified tolerances. The laboratory's capability across push and pull force, absolute, gauge and differential pressure, and vacuum ranges allows teams to align calibration scope with actual operating conditions and defined measurement points.

Updated reference values for calibrated instruments
Calibration provides updated reference values for force, pressure and vacuum instruments used in testing and production. When measurement drift or uncertainty raises doubt about previous results, recalibration provides a defensible reference point that helps clarify whether deviations are instrument- or process-related. The laboratory's accredited status and its traceability to international primary standards provide documented calibration results for technical documentation and quality systems.

Use cases

Calibrate force, pressure and vacuum instruments to provide traceable measurement results for testing, production and technical documentation.

Calibration of mechanical test equipment

Calibrate force transducers, dynamometers, jacks and related devices in push and pull configurations to confirm that applied loads are within specified tolerances. The results are used to validate tensile and compression testing, confirm load application in production environments and document that mechanical performance tests are based on reliable reference measurements. This supports defensible test reports and reduces uncertainty in material or product qualification decisions.

Pressure instrument calibration for process control

Calibrate absolute, gauge and differential pressure instruments using relevant media to align results with operating conditions. This enables engineering and production teams to confirm that process limits, safety thresholds and performance data are based on traceable measurements. The documented outcomes support stable operations, investigation of deviations and verification of pressure-dependent systems in both gas and liquid applications.

Vacuum measurement confirmation for controlled environments

Perform vacuum calibration og all kinds of vacuum meters, including Capacitance Diaphragm Gauge (CDG), Spinning Rotor Gauge (SRG), Hot-Cathode ionisation, Cold-Cathode ionisation and Pirani to verify instruments used in research, manufacturing or controlled technical environments. Calibration results provide a traceable reference for vacuum levels used in testing or production, supporting comparison over time and between sites. This strengthens documentation where vacuum conditions are part of validation, development or regulated procedures.

Uncertainty: 6 µPa in high vacuum to 0.3 % in rough and medium ranges

Vacuum calibration method and chamber design
Calibration is performed by direct comparison between the test gauge and one or more reference gauges with overlapping measurement ranges to minimise uncertainty. The system includes a calibration chamber with eight equatorial flanges allowing simultaneous connection of reference and test instruments. A pump-and-gas-control system dynamically regulates pressure. Calibrations are carried out either statically, by isolating the chamber at a set pressure, or in a stationary balance, maintaining stable flow until equilibrium is reached.

Reference traceability
Traceable to DFM and international primary standards through accredited reference transducers, deadweight testers and pressure balances.

Controlled environment for stable calibration
Temperature and humidity are maintained within narrow limits to minimise elastic deformation, medium viscosity variation and buoyancy effects. Environmental conditions are monitored continuously within the accredited uncertainty budget.

Calibration of irregular and heavy components
The laboratory calibrates asymmetrical or non-standard mechanical components used as reference loads in force and pressure calibration systems. Dedicated handling equipment enables accurate alignment and safe calibration of weights up to one tonne.

Facility setup

Configure force, pressure and vacuum calibration setups across ranges, media and connection types to match instrument design and operating conditions, ensuring relevant, traceable results for technical decisions and documentation.

Push and pull force configurations

Calibration setups can be arranged for both tension and compression measurements, enabling verification of instruments used in different load directions. This ensures that force transducers, dynamometers, and related devices are calibrated under conditions that reflect their real applications, supporting reliable mechanical test results and load validation.

Laboratory and on-site calibration options

Calibration can be performed either within the laboratory environment or at the customer's site for selected force applications. This flexibility allows organisations to maintain traceability for installed equipment or large systems that cannot be easily transported, supporting operational continuity and documented compliance.

Absolute, gauge and differential pressure setups

Pressure calibration can be configured based on whether the instrument measures absolute, gauge, or differential pressure. Aligning the setup to the measurement principle ensures that uncertainty and reference conditions reflect actual use, strengthening the validity of process data and safety-related limits.

Selectable pressure media

Calibration can be carried out using air, nitrogen, oil, or isopropyl alcohol, depending on the instrument type and range. Matching the calibration medium to the intended operating medium reduces deviations linked to fluid properties and supports defensible documentation for both gas and liquid systems.

Vacuum calibration methods and balance modes

Vacuum instruments can be calibrated statically or at a stationary balance, depending on the required measuring range. This enables adaptation to different vacuum levels and instrument technologies, ensuring that readings used in controlled environments or research applications are traceable and comparable.

Multiple connection flange types

The facility supports different connection flange types for vacuum instrumentation. This allows instruments with varying mechanical interfaces to be mounted correctly during calibration, helping prevent installation-related errors and ensuring that measurement performance is evaluated under appropriate mechanical conditions.
