Constellation PowerLabs
Testing & Calibration Lab Services

Calibration

As the leading calibrations lab in the USA, we provide both in-house and onsite calibration services across North America. ISO 17025 accredited, we hold one of the widest scopes of accreditation across different disciplines, supporting accurate measurements across a broad range of applications.

High Voltage Calibration Services

We are one of the only high voltage labs in the Americas that can provide the level of ISO 17025 high current and high voltage calibrations, along with a team of seasoned technicians and advanced equipment for bringing maximum accuracy.

Parts Quality Initiative™

PQI® testing verifies defective parts before installation, reducing downtime, labor and logistics costs, and allowing for replacement of parts under warranty. It also acts as a predictive maintenance service by identifying components that are likely to fail, allowing proactive planning and smarter procurement decisions.

Failure Analysis

As part of our failure analysis services, we use advanced equipment and decades of documented failure records to quickly identify the root cause to support your failure analysis investigation, so your team can take the right corrective action.

Commercial Grade Dedication Testing

Our calibration lab tests over 12,000 components annually for nuclear safety, offering unmatched reliability and cost-effective alternatives to OEM replacements. Commercial Grade Dedication Testing services qualify critical components for safety-related use while supporting compliance and performance standards.

Metallurgical & Material Analysis

We are not only a calibration lab, we also provide critical testing. Our mechanical testing services determine key material properties such as strength and durability, while metallurgical analysis offers insight into the structure of metallic materials. We also perform chemical testing to verify elemental composition and support material verification needs.

Contaminated Hot Lab

Our in-house radiological hot lab enables us as an approved nuclear supplier to support calibrations and testing of your radiologically contaminated equipment. We are also equipped to provide you accredited calibrations as well.

ISO 17025 Calibrations

We take pride in delivering high-quality service backed by technical excellence. Our full-service laboratory is equipped with advanced measurement capabilities and holds an A2LA accreditation to ISO 17025, allowing us to meet your accredited calibration requirements.

Chemical Analysis & Testing

Our testing and calibration lab provides chemical analysis that includes contamination detection, identification of unknown chemicals, or verification of known chemicals to support your quality control monitoring. Contact us to see how we can best support you today!
