Pressure Gauge Calibration Services
Maintain Your Equipment’s Integrity
Pressure gauges are sensitive instruments that demand routine maintenance and accuracy verification for optimal performance. At Constellation PowerLabs, we offer pressure gauge calibration services for industries where precision is a priority. We deliver accurate measurements for your most critical instruments, handling pressures up to 40,000 PSI.
While pressure gauge calibration is part of what we do, our capabilities extend far beyond:
- Robust Certifications & Quality Requirements: Including 17025 accredited calibrations (A2LA accredited), 10 CFR 50 Appendix B, 10 CFR 21, NQA-1, and ANSI N45.2.
- Convenient OneLab Customer Portal: For easy access to certificates and tracking.
- One-Stop Shop: Diverse calibration services and testing capabilities mean you can send all your equipment to a single provider.
- Extensive National & International Reach: With six labs strategically located across the U.S., we are able to provide seamless support throughout the U.S. and Canada.

Our Certified Process for Pressure Gauge Calibration Services
Our process enables collaboration, offers routine maintenance reminders, and securely stores records, keeping you audit-ready and compliant. Here’s how we make pressure gauge calibration services simple, efficient, and transparent through every step:
Consultation and Quotation
Our experts assess your equipment and compliance needs, providing a free quote for ISO 17025 or NIST-traceable calibrations.
Schedule In-Lab or Onsite Calibration
Ship your instruments securely to one of our accredited labs, or request onsite service for high-volume calibration needs. We serve clients across the U.S., including Texas, South Carolina, North Carolina, and beyond.
Calibrate and Certify
With proper warm-up, our technicians exercise the unit under test, zeroing both the instrument and reference if needed. Pressure is applied incrementally across the range per manufacturer specifications, comparing readings to certified standards at each point. Next, a final hysteresis check is performed, and all data is recorded.
Documentation
Easily download certificates once your pressure gauge calibration services are complete. Access them anytime through our OneLab customer portal for audits or quality records.
OnSites and In-Lab Capabilities
Constellation PowerLabs offers flexible measurement solutions tailored to your operational needs. Whether you’re shipping equipment to one of our accredited labs or scheduling onsite services for large-scale systems, we’ve got the bandwidth to support you.
As a full-service electrical and mechanical testing laboratory, we’re accredited by A2LA to ISO 17025 standards, delivering accuracy and reliability every time.
Onsite Field Visits
Ideal for bulk quantities or large-scale systems that are difficult to transport. Our field teams deliver precise, on-location calibrations to keep your equipment compliant and operations running smoothly.
Common onsite calibrations include:
- High-volume instrument batches
- Large or fixed systems (e.g., high voltage calibrations such as HV testing equipment, transformers and impulse test systems)
- Highly sensitive or delicate equipment that requires minimal handling
In-Lab Service
Best suited for most pressure gauges and compact instruments. Our ISO 17025-accredited labs across the U.S. provide accurate results, secure logistics, and real-time certificate access through our OneLab portal.
Common in-lab measurements include:
- Small to mid-sized equipment
- Instruments that are easy and cost-effective to ship
- For larger systems, onsite service is recommended
