Calibration of vacuum sensors (vacuum gauges) based on piezoresistive, Pirani, inverted magnetron, Bayard-Alpert, hot cathode, and extractor principles

Precision You Can Rely On – Confidence You Can Measure

In any vacuum-based process, accuracy isn’t optional—it’s essential. Whether you're in research, manufacturing, quality control, or testing, the performance of your vacuum systems depends on the reliable calibration of your vacuum gauges. Our professional calibration service ensures that your equipment consistently delivers the precision required to meet today’s demanding technical and regulatory standards.

What We Offer

✅ Calibration for All Vacuum Gauges and Sensors
We calibrate a wide variety of vacuum measurement devices, regardless of brand or model, across a full measurement range—from high vacuum to ambient pressure.

✅ Traceable Standards, Certified Results
All calibration procedures are performed using reference gauges that are directly traceable to national and international standards (DAkkS, ISO, etc.). You receive a detailed calibration certificate, including uncertainty analysis, to support your internal quality systems and audits.

✅ Calibration Options That Fit Your Needs
Choose between:

• Standard Calibration (cost-effective, fast turnaround)

• DAkkS-Accredited Calibration (for regulated industries and ISO compliance)

✅ Measurement Range Coverage
Our facilities support calibrations over a broad vacuum range—from 1,000 mbar (atmospheric pressure) down to 10⁻⁶ mbar (high vacuum).

Why Regular Calibration Matters

• Ensure Process Accuracy
  Even minor measurement drifts can lead to poor process control, production defects, or invalid data. Regular calibration keeps your system performing to spec.

• Maintain Compliance & Certification
  For industries like pharmaceuticals, aerospace, food processing, and clean energy, traceable calibration is not just best practice—it’s a regulatory requirement.

• Protect Your Investment
  Calibrated vacuum systems help extend equipment lifespan, reduce downtime, and prevent premature pump failure due to improper operating conditions.
