HOWELL LABORATORIES INC

Howell Laboratories Inc. specializes in the design and manufacturing of precision instrumentation and environmental control systems for defense and homeland security applications. Their core capabilities center on developing sensors, transmitters, and control modules for measuring humidity, pressure, dew point, and electrical signals in demanding operational environments. The company produces critical components such as humidity transmitter groups, dew point indicators, membrane dehydrators, and valve assemblies, demonstrating deep expertise in environmental monitoring, signal conditioning, and industrial process instrumentation. Their technical proficiency spans aerospace-grade sensor integration, hermetic sealing, and ruggedized electronics manufacturing, with a focus on reliability under extreme conditions. A key differentiator is their ability to deliver custom-engineered instrumentation that meets stringent military and federal specifications, often for mission-critical systems deployed in maritime, airborne, and expeditionary settings. The contractor maintains a strong relationship with the Department of Defense, supplying specialized equipment for naval, aeronautical, and logistics systems. They also support the Department of Homeland Security with environmental monitoring devices used in maritime and border security operations. Their work consistently involves high-integrity components requiring precise calibration and environmental resilience. Industry focus is anchored in instrument manufacturing for electrical and environmental measurement (NAICS 334515, 334511, 334512), alongside commercial and industrial refrigeration equipment (333415) and shipbuilding-related subsystems (336611). This positions them as a niche supplier of mission-critical sensing and climate control hardware for defense and infrastructure systems. Howell Laboratories Inc. is a small business based in Bridgton, Maine, operating under a 2L entity structure. While no federal certifications are listed, their consistent performance on classified and controlled defense contracts indicates established compliance with federal manufacturing and quality standards. Their geographic presence supports regional defense supply chains with specialized precision manufacturing capabilities.
