Founded in 1986 with a strong commitment to research and development, Quatrosense Environmental Ltd. (QEL) is a privately held, North American Corporation. The 18,000 square foot head office and factory is located in Richmond, Ontario, just outside Ottawa, Canada’s capital. QEL manufactures and markets a wide selection of instrumentation for hazardous gas detection. With this equipment QEL assists its customers in the protection of life, property, and the environment.

QEL has focused its growing resources on diversification of the product line. Indoor air quality and refrigerant leak gas detection products were developed that today produce large volumes of sales. Specialized equipment and turnkey systems were also developed for numerous markets including the Mining, Petrochemical, Breweries, and Landfill Industry. New gas sensors, design and packaging improvements increased the quality and reliability of the industrial products throughout the 1990’s. This commitment to innovation has served as a platform to launch QEL into the next decade. Commitment has also produced a number of strategic alliances. One of QEL’s most recognizable alliances is with NASA and the United Space Alliance (USA). It is here that leading edge products have been developed that are critical to the safety and integrity of the U.S. Shuttle program. The level of quality required for these products becomes standard throughout QEL’s operations. This has produced an ISO 9001 compliant quality system as recognized by NASA for instrumentation used in support of the Shuttle program.

QEL values its customers. Customer feedback fuels research projects, new product development, and product enhancements. QEL today is an exciting company undergoing constant change for improvement. Production facilities are continually upgraded. The international Engineering staff produces a constant stream of new product development and enhancement to existing products. The Sales and Marketing department has been expanded to include a comprehensive Customer Service Team. They provide customer support in everything from application assistance to routine field maintenance and service of existing systems

QEL is dedicated to continuing its leadership in its field. We will maintain this through a dynamic commitment to research, targeting new technologies, improving the quality of its products and services, and strengthening the skills of its people. Our objective is both simple and progressive; to further develop QEL’s position in supplying environmental solutions to the world well into the twenty-first century.
