What is Pressure & Vacuum Calibration?

Our NABL-accredited services validate pressure and vacuum instruments, including digital/analog pressure gauges, vacuum transducers, Magnehelic gauges, pressure switches, and safety relief valves (0.01 mbar to 700 bar, ±0.025% FS accuracy), ensuring precision in measurements for applications.

Why is it Critical?

Accurate pressure and vacuum measurements are vital for sterilization, fermentation, and sterile manufacturing processes, ensuring compliance with GMP standards and maintaining process safety and product quality.

Regulatory Compliance & Global Standards

Calibration laboratories must adhere to stringent regulatory and quality standards to ensure accurate, reliable, and traceable measurement results. These standards not only assure data integrity and measurement validity but also support compliance with international regulatory bodies and customer-specific requirements.

  • ISO/IEC 17025:2017: General requirements for the competence of testing and calibration laboratories. It ensures valid results, technical proficiency, and traceability.
  • 21 CFR Part 11 (FDA): Governs electronic records and signatures—applicable if digital systems are used in calibration documentation.
  • Good Manufacturing Practices (GMP): Ensures measurement equipment used in regulated environments (like pharma) is properly calibrated and traceable.
  • ISO/IEC Guide 98 (GUM): Guide to the Expression of Uncertainty in Measurement – for reporting uncertainty.
  • DKD-R 6-1/ DAkkS-DKD: Pressure calibrations are performed as per applicable guidelines for pressure calibration.

Frequently Asked Questions

Frequently Asked Questions

What is pressure and vacuum calibration?

Pressure and vacuum calibration is the process of verifying and adjusting instruments that measure positive or negative pressure (vacuum), ensuring they provide accurate and traceable readings as per defined standards.

What is the typical range of calibration offered?

Our lab typically supports:
• Vacuum range: from 0 to -0.9 bar
• Pressure range: from 0 to 700 bar

Are your calibration results traceable to national or international standards?

Yes. All calibrations are traceable to:
• NPL (National Physical Laboratory, India)
• NIST (USA) or other ILAC-MRA member NMIs
Calibration is performed under ISO/IEC 17025:2017 compliance.

How often should pressure/vacuum instruments be calibrated?

Typically once every 12 months, unless otherwise recommended by:
• Manufacturer guidelines
• Regulatory body requirements
• Instrument usage frequency or criticality

Do you provide on-site pressure calibration?

Yes, we offer on-site calibration for certain instruments using portable calibrators, especially for large equipment or in regulated environments like pharma plants or industrial units.

Do you offer a statement of compliance or pass/fail report?

Yes. On request, we provide a Statement of Conformity or pass/fail evaluation based on specified tolerance or regulatory standards.

Can you calibrate pressure instruments used in pharmaceutical or cleanroom environments?

Yes. We provide calibration services compliant with:
• WHO-GMP, USFDA, ISO 13485
• We also offer on-site calibration in controlled/cleanroom environments
