O2 Analyzers

O2 Analyzers for PPM and % Oxygen Measurement

Applied Sensing Technologies (AST) delivers advanced O2 Analyzers engineered for precise measurement of oxygen at both PPM and percent levels. In industrial environments where oxygen control directly affects safety and product quality, accurate monitoring becomes essential. For this reason, AST designs its analyzers to perform reliably in inert gases, gaseous hydrocarbons, and gas streams containing reactive gases such as CO₂. As a result, operators maintain tighter process control and reduce operational risk.

Supporting Critical Industrial Applications

Across industries, oxygen measurement requirements vary significantly. Therefore, AST offers solutions that adapt to multiple applications while maintaining consistent performance.

For continuous process monitoring, AST O2 analyzers provide real-time oxygen data that helps protect sensitive operations. In glove boxes and other controlled atmospheres, they maintain low oxygen levels to safeguard materials and processes. Similarly, in food packaging systems, they verify gas composition to preserve freshness and extend shelf life.

Beyond manufacturing environments, AST analyzers also support gas purification processes. During CO₂ purification, for example, precise oxygen monitoring ensures product quality and system efficiency. In medical settings, accurate measurement becomes even more critical. Consequently, AST oxygen analyzers verify medical-grade oxygen and perform oxygen purity analysis with dependable accuracy. At the same time, portable units allow safety teams to measure oxygen concentration in confined spaces before entry, reducing the risk of hazardous exposure.

Flexible Configurations for Every Requirement

Because different applications demand different installation types, AST provides a complete range of analyzer configurations.

On-line PPM O₂ analyzers enable continuous, fixed installation monitoring for process control.

Portable PPM O₂ analyzers offer flexibility for field measurements and spot checks.

%O₂ analyzers support higher concentration measurements.

Oxygen purity analyzers verify high-purity oxygen streams in medical and industrial systems.

Moreover, for operations in hazardous locations, AST offers optional intrinsically safe designs compliant with Class I, Division I, Group IIC requirements. This ensures safe and reliable performance even in environments where explosive gases may be present.

Proven Technology at the Core

While configuration flexibility is important, sensor performance remains the foundation of accuracy. For that reason, AST integrates industry-proven electrochemical micro fuel cell technology into its analyzers. Designed specifically for oxygen measurement, these sensors deliver fast response and excellent stability across both sub-PPM and percent ranges.

Importantly, AST designs, develops, and manufactures these sensors in the USA. This vertical integration strengthens quality control and ensures long-term reliability in demanding applications.

Precision, Reliability, and Control

Ultimately, effective oxygen monitoring requires more than measurement—it requires confidence. By combining advanced sensor technology with rugged analyzer design, AST provides dependable solutions for industrial, medical, and safety applications alike. Whether monitoring trace oxygen in inert gas systems or verifying oxygen purity in medical supply lines, AST enables operators to act quickly, maintain compliance, and protect critical processes.
