Armstrong Monitoring, an Ottawa based, ISO-9001 registered manufacturer of high quality gas sensing equipment, prides itself in meeting the needs its customers.

Since its inception, Armstrong Monitoring has worked in concert with industry and leading research organizations in the design and commercialization of innovative new technologies and products for a wide range of applications. Armstrong Monitoring’s diverse product line features equipment designed to detect and monitor an extensive list of gases including CO, NO₂, O₂, refrigerants, and combustible gases, such as hydrogen, propane, methane and methanol, plus a variety of exotic species. Equipment choices range from simple, building block sensor elements and transmitters, to complete, integrated, turnkey systems.

In January, 1981 Armstrong Monitoring sprung from Leak-X Corp. Named after our founder, Lawrence J. Armstrong, the company was launched with an emphasis on the budding hazardous gas detection market.

For over 40 years Armstrong Monitoring has manufactured a highly dependable and cost effective line of detection equipment. We are proud to say that much of that equipment is still in service today.

In 1984 Armstrong Monitoring’s service department was established, and has developed into a respected multi-vendor service group, offering both factory and field service with global reach.

In 1998 Armstrong Monitoring first became certified to ISO 9001 standard and has consistently maintained adherence and certification to this standard.

In 2004 Armstrong Monitoring was acquired by a group of successful local investors from Ottawa’s technology sector. The new ownership group has worked to streamline the product offering and simplify the manufacturing process.

In 2014, Armstrong Monitoring was acquired by a team specializing in the development of new technologies. Building on the wide customer and product base, and ISO certified processes, Armstrong Monitoring developed a new vision for gas detection. It developed a new common platform where the equipment is modular, upgradeable, backwards compatible and easy to maintain and service and that will support any type of gas and gas sensing technology. This modularity means that advances in technology can rapidly be integrated into the equipment, and into systems already installed. Supported by Adaptical™, the patent pending calibration routine, the equipment can be serviced by anyone, reducing the need for specialized skilled trades in remote or challenging sites.
