About Analytical Industries Inc.

From humble beginnings in a California garage, with nothing more than a sheet of paper and a bold engineering vision, Analytical Industries has grown into a global leader in high-performance oxygen sensors and gas analyzers for the world’s most demanding applications.

Founded on a spirit of innovation and technical curiosity, developed its own proprietary electrochemical oxygen sensor technology in its earliest days. That breakthrough became the foundation for a comprehensive range of industry-leading trace, ultra-trace, and high-purity oxygen analyzers. Today, as a proud DwyerOmega brand, Analytical Industries continues to push the boundaries of gas-measurement performance, engineering every solution around the real-world challenges faced by its customers.

A Legacy of Innovation

For more than 30 years, Analytical Industries has specialised in the design and manufacture of high-performance oxygen sensors and gas analyzers. Our technologies support a wide spectrum of applications, including:

• • Industrial process control and safety
  • Specialty and ultra-high-purity gas production
  • Semiconductor and advanced manufacturing environments
  • Breathing-air quality monitoring for diving and medical devices

Across each of these sectors, Analytical Industries products are trusted for their accuracy, stability, and long-term reliability in environments where failure is not an option.

Our History

Founded in 1990, Analytical Industries Inc. began as a small team of engineers dedicated to redefining what was possible in oxygen measurement. Over the decades, Analytical Industries has evolved into a globally recognised supplier, serving customers worldwide while maintaining its commitment to Made in USA design and manufacturing.

Despite this growth, Analytical Industries has never lost sight of its roots. Engineering excellence, practical problem-solving, and close collaboration with customers remain central to how we develop and deliver our products today.

What We Do

At Analytical Industries, innovation is not a department, it is a mindset embedded throughout the organisation. Our R&D teams continually explore new sensor materials, electrochemical designs, and analytical techniques to advance the performance, accuracy, and reliability of oxygen and gas measurement technologies.

Every analyzer and sensor is engineered with the end application in mind. From component selection to system architecture, our designs prioritise:

• • Measurement accuracy and repeatability
  • Long operational life with minimal maintenance
  • Stability in harsh, safety-critical, or ultra-clean environments

This disciplined, engineering-led approach ensures our customers receive solutions they can rely on day after day.

Quality, Integrity, and Customer Focus

Quality is built into the heart of every Analytical Industries product. Rigorous in-house testing, calibration, and verification processes ensure each instrument meets exacting performance standards before it leaves our facility.

Equally important is how we work with our customers. We believe strong partnerships are built on integrity, transparency, and responsiveness. Whether supporting a new product evaluation, custom application, or long-term installation, our team is committed to providing clear guidance, technical expertise, and dependable support.

Quality and Compliance

Analytical Industries operates under a comprehensive quality management system and is certified to ISO 9001 and ISO 13485 standards. Many Analytical Industries products are FDA-approved and MDSAP-compliant, supporting use in regulated medical and safety-critical applications.

We maintain strict calibration, traceability, and documentation procedures to ensure every sensor and analyzer meets or exceeds applicable industry and regulatory requirements, providing confidence in performance, compliance, and long-term reliability.
