Gauge AcquiresAirX Testing Services

AirX Testing Services enters its next chapter with Gauge Industrial Group.

After more than thirty years as an independent firm, AirX Testing Services is joining Gauge Industrial Group to expand its capabilities, invest in its people, and bring new technology to industrial compliance. Based in Ventura County, AirX provides air emissions testing and compliance services to industrial facilities across California. The firm has built a strong reputation, supported by longstanding customer relationships, deep technical expertise, and an experienced team. AirX brings decades of industry experience, an established customer base, and the technical capabilities that define the firms we seek to partner with at Gauge.

A Leader in Air Emissions Testing

Industrial facilities must demonstrate compliance with increasingly complex environmental and air quality regulations. When boilers, engines, dryers, flares, and refinery units require emissions testing, the results must be accurate, defensible, and accepted by regulatory agencies.

AirX has delivered these services since 1995, maintaining its air district laboratory approval throughout that period. The firm is also one of a limited number of independent California providers capable of performing a broad range of test methods in-house, giving customers access to specialized technical capabilities through a single partner.

The strength of AirX’s business is reflected in its customer relationships including those that span decades, driven by permit requirements and established testing schedules. The firm serves customers across aggregates and asphalt, municipal services and landfills, oil and gas, manufacturing, and other industrial sectors. These longstanding relationships provide a strong foundation for AirX’s continued growth.

Continuing a Legacy of Excellence

Ryan and Dave have spent decades establishing AirX’s reputation, strong customer relationships, and developing the team and capabilities that support the business today.

We will build on AirX’s legacy through investment in people, equipment, and technology while preserving the expertise, relationships, and continuity that make the firm successful.

We are grateful to Ryan and Dave for the opportunity to continue AirX’s growth and we look forward to supporting the team moving forward.

Investing in People and Capabilities

AirX’s technical expertise and customer relationships are crucial to its reputation. Gauge will enable the team with more resources, greater capacity, and frontier level AI-native technology, while maintaining the high standards of service customers expect. We intend to introduce enhanced customer tooling and real-time visibility that set a new standard for the industry.

We’re expanding the AirX field team to serve more customers and take on additional work. As part of Gauge, the AirX team will have access to new opportunities for professional growth and the support to continue developing their expertise.

Investing in Growth

Gauge takes a long-term approach to building industrial compliance firms. We invest in the people, equipment, and technology required to expand their capabilities, serve more customers, and build stronger firms.

For AirX, that means hiring additional field personnel, upgrading equipment, expanding its in-house testing capabilities, and deepening its presence across California’s South Coast Air Basin. These investments will allow AirX to serve more customers, take on a broader range of work, and strengthen its position in the region.

As the company grows, maintaining the same local and personal feel that customers value is equally important. Our goal is to expand AirX’s capabilities while preserving the close customer relationships and personalized service that make it successful.

A key part of the growth strategy is Forge, Gauge’s AI-native operating platform. Forge streamlines scheduling, report preparation, and permit tracking, allowing the team to spend more time on technical work and customer service. Deployed at AirX within days of closing, Forge brings the firm’s workflows and hundreds of thousands of historical records onto the AI-native platform to increase efficiency.

By combining AirX’s technical expertise with modern technology, we believe the firm can improve operational efficiency, strengthen the customer experience, and expand its capacity while building for long-term growth.

The Next Chapter

For AirX customers, the commitment remains the same: the people, technical standards, and service you rely on, supported by additional investment and expanded capabilities.

Gauge partners with established industrial compliance firms to help them grow, invest in their people, and bring modern technology to essential industries. AirX is an important addition to that effort, and we look forward to building on its reputation and serving its customers for years to come.

We are proud to welcome AirX to Gauge Industrial Group.
