At SSO₂, our application notes provide practical insights into how oxygen sensors, O₂ analyzers, and gas monitors are used in real-world environments. These guides help engineers, safety professionals, and facility managers understand the best practices, risks, and system design considerations for different industrial and safety applications.
Oxygen concentration in normal air is about 20.9%, but in environments storing or using inert gases (like nitrogen or argon), this can drop to dangerous levels without warning. Humans cannot reliably sense low oxygen — so our application notes explain how to place fixed ambient air monitors (such as the OMD-351 series) to provide early warning when oxygen falls below safe thresholds.

We recommend mounting monitors 3–5 feet off the ground and keeping them 3–5 feet away from gas cylinders, with multiple units every 400–600 ft² for full coverage. SSO2
Confined spaces — like storage tanks, pits, and enclosed process vessels — often present serious oxygen-deficiency hazards. Our application notes outline how to use both portable and fixed oxygen monitors to detect unsafe oxygen levels, deploy alarms, and integrate the devices into safety protocols. It is critical to ensure that oxygen levels are measured before personnel enter and continuously monitored while they stay inside.
We strive to support our customers with application-specific products and services. This database includes links to many of our recommended sensor and instrumentation solutions for specific industries, which provide an overview of our gas measurement solutions.
