In aerospace heat treatment, accuracy is not an aspiration — it is a requirement that must be demonstrated, documented, and defended during every audit. The systems behind that accuracy often operate quietly in the background, yet they determine whether a process, and ultimately a part, is accepted or rejected. That reality led Andrew Bassett to establish Aerospace Testing & Pyrometry, Inc. (ATP) in 2007, with a singular focus on helping manufacturers meet the increasingly exacting demands of aerospace pyrometry and compliance.
From its headquarters in Easton, Pennsylvania, the company was built around deep technical specialization rather than broad generalization. Early work centered on aerospace heat treaters navigating AMS2750 requirements, Nadcap audits, and client-specific specifications that left little margin for interpretation. Over time, that expertise expanded to support a wider range of thermal processing environments, but the core mission remained unchanged: ensure temperature measurement systems are accurate, defensible, and audit ready.
Today, ATP supports heat treaters across aerospace, automotive, medical, and industrial manufacturing, providing services that extend far beyond routine calibration. Its pyrometry and calibration offerings include system accuracy tests (SATs), temperature uniformity surveys (TUS), and calibration of temperature, humidity, pressure, and vacuum measurement systems, performed both on-site and in laboratory environments. The company operates under an ISO/IEC 17025:2017 accredited quality management system, reinforcing their commitment to continuous improvement, accuracy, and repeatability.
The differentiating factor for ATP is its ability to provide more than calibration services, namely audit-ready compliance support built specifically for aerospace and thermal processing requirements. The company offers a fully integrated service model that simplifies compliance management, combining on-site pyrometry and calibration, consulting, training, and compliance software. This key factor promotes long-term compliance stability and accountability.

A notable development in the company’s offerings is its Aerospace Compliance Software (ACS), developed in-house by pyrometry specialists. Unlike generic quality or calibration platforms, ACS was designed specifically around AMS2750 workflows and Nadcap audit logic. The software aligns with how auditors review data and how thermal processing facilities manage instruments, surveys, and records. Features, such as leak rate testing for vacuum furnaces, preventive maintenance tracking, sensor management, and role-based access, reflect the practical challenges faced by compliance teams. For many users, ACS reduces reliance on spreadsheets and manual workarounds, improving traceability and audit readiness.
Nationwide coverage supports this integrated model. With regional offices and laboratories across the United States, ATP combines responsive local service with centralized technical oversight. This structure minimizes downtime while maintaining consistent methodology and documentation — an important balance for manufacturers operating under tight production schedules and audit cycles.
Across a range of industries, the company’s approach goes beyond addressing immediate issues, focusing on establishing long-term confidence. Clients rely on ATP not only to verify accuracy, but to help them move from reactive audit preparation toward proactive process control. That shift reduces risk, improves consistency, and allows quality teams to focus on continuous improvement rather than last-minute corrections.
Looking ahead, ATP plans to continue expanding its compliance solutions, with ongoing development of ACS and deeper integration of calibration, testing, and documentation workflows. As aerospace and manufacturing specifications grow more complex, the company’s future focus remains grounded in the same principle that shaped its founding: when compliance matters, technical clarity and defensible data are essential.
