Vacuum Gauge Calibration Services By Unique Vacuum Solutions

Pressure & vacuum monitoring comes with unique safety, compliance and maintenance demands. That’s why Unique Vacuum Solutions wants to ensure that you have expertly calibrated equipment. At our works, we perform vacuum gauge calibrations to support critical objectives – from safeguarding product stability to ensuring research validity. Our talented experts have the knowledge to conduct ultra-accurate calibrations so your process vacuum equipment delivers the precision you need.

Calibrate Vacuum Gauges for High Performance
  • Ensure production quality or pinpoint issues in production.
  • Receive correct gauge readings that contribute to uptime and safety.
  • Keep equipment certifications up to date in regulated environments.
  • Depend on accurate instruments during monitoring or testing.
  • Prepare newly purchased devices for duty and verify application compatibility.
  • Identify and correct equipment errors – before services and processes are impacted.
Why Choose Unique Vacuum Solutions Calibration?

Our extensive vacuum calibration services include evaluating devices that report vacuum, absolute and gauge measurements. Zero and span adjustments where ever necessary in consultation with customer. We calibrate all types of vacuum measurement instrument, including digital and analog vacuum gauge calibrations

  • Capacitance manometers from full scale range 1 torr and 1 mbar.
  • Pirani vacuum measurement gauges: range 10e-4 mbar to 20 mbar.
  • Cold cathode vacuum gauges: 10e-2 mbar to 10e-6 mbar range.
  • Hand held battery operated refrigeration vacuum gauges.

    Unique vacuum solutions will work with you to establish a schedule for each vacuum measurement device that requires recalibration. We can then provide timely vacuum calibration notifications. You can also rely on rapid turnarounds, with many devices back on the job in just five business days.

Job execution

Unique Vacuum Solutions has trained and expert calibration staff who carry the master reference vacuum gauge along with the high vacuum generation system (turbo pump based) to the customer site.

The master calibration references
  • for medium vacuum range up to 1 micro bar or 0.001 mbar will be capacitance manometer BARATRON
  • for high vacuum measurement from 0.01 mbar to 10e-6 mbar the master will be the full range gauges.
  • All the masters will have the valid NPL or NIST traceable certificates.
Lead time to attend the calibration

Lead time to attend the calibration from the date of receipt of confirmed order: 04 days for the metro and major cities, 8 working days for the non metro and tier II cities.

The calibration procedure and master calibration reference certificates will be submitted prior to the commencement of the calibration.

The procedure

The INSTUMENT UNDER CALIBRATION (IUC) is assembled along the master gauge, needle vacuum valve

To ensure the ultimate base pressure of 10-5mbar pre-evacuation, we shall be carrying one set of high vacuum gauge set for measuring the 10e-5 mbar during calibration proceedings.

  1. The required reference instruments, vacuum generation system which consists of turbo molecular vacuum pumping system with all vacuum connections, calibration dome and fittings will be brought by UVS engineer.
  2. We shall submit the calibration report of the vacuum gauge upon completion of the calibration.
  3. Calibration range for vacuum gauge: 10mbar to 10e-3 mbar. OR 10000 micro bar to 1 micro bar.
