Rezonans Kalibrasyon — Pressure Calibration Laboratuvarı

As Rezonans Kalibrasyon, we provide international-standard pressure calibration solutions to maximize the efficiency and safety of your industrial processes. Whether in our laboratory environment or directly on-site (in-situ calibration), we perform measurements using the comparison method guided by Euramet cg-17, utilizing high-precision reference manometers and vacuum gauges.

Why Choose Rezonans Kalibrasyon?

  • Wide Measurement Range: We offer services across a broad spectrum ranging from -1 bar to 700 bar.
  • Dual-Phase Calibration Media: We ensure reliable measurements using dry air for sensitive low pressures (-1 bar to 40 bar) and pure water for high-pressure requirements (40 bar to 700 bar).
  • Flexible Unit Support: We provide professional reporting in all industrial units, including mbar, Pa, mmHg, psi, kPa, and MPa.
  • Accredited and Certified Solutions: All our calibration processes are traceable, certified, and fully compliant with audits.

Frequently Asked Questions

How often should pressure calibration be performed?

In accordance with general industrial standards and Euramet cg-17 guidance, it is recommended to calibrate pressure measuring devices at least once a year. However, depending on usage intensity, criticality, and environmental conditions, this interval may be reduced to 6 months. Regular calibration prevents production losses and safety risks caused by faulty measurements.

What is the difference between on-site (field) calibration and laboratory calibration?

Laboratory calibration is performed in a controlled environment where temperature and humidity are stabilized and isolated from external factors, ensuring the highest precision. Field calibration is a service performed at your facility by our expert team when equipment cannot be disassembled or production cannot be halted. Rezonans Kalibrasyon provides certified services with international traceability for both methods.

Why is the difference between calibrations performed with pure water versus air important?

For measurement accuracy, the calibration media must be compatible with the device’s operating principle. Generally, dry air is used for low-pressure and sensitive devices (pneumatic systems) between -1 bar and 40 bar. In high-pressure industrial systems and safety valve tests, pure water (hydraulic) is preferred between 40 bar and 700 bar to ensure safety and stability.

Why are safety relief valve testing and calibration mandatory?

Safety valves are the last line of defense preventing pressurized vessels and piping from exploding under overpressure. Testing whether these valves open at the designated set point is a legal requirement for both Occupational Health and Safety (OHS) regulations and equipment longevity. Our company performs these tests with full certification.

What information is included in a calibration certificate?

The calibration certificates we issue include the device’s measurement results, referenced standards (such as Euramet cg-17), measurement uncertainty, environmental conditions, and the compliance status within the device’s tolerance values. These documents are legal records that prove your device’s accuracy during quality audits (ISO 9001, etc.) and official inspections.
