Oxygen Analyzers and Transmitters

Oxygen Analyzers and Transmitters

Applied Sensing Technologies (AST) manufactures high-performance Oxygen Analyzers and Transmitters for accurate measurement from sub-PPM to percent oxygen levels. As a result, operators can continuously monitor inert gases, gaseous hydrocarbons, and gas streams containing reactive gases such as CO₂.

AST instruments support a wide range of applications. For example, users verify gas composition in glove boxes and food packaging systems. In medical settings, healthcare providers confirm oxygen purity and monitor breathing gases. Meanwhile, portable analyzers support CO₂ purification processes, and handheld units help personnel verify safe oxygen levels before entering confined spaces.

For hazardous locations, AST offers 4–20 mA loop-powered O₂ transmitters designed to meet intrinsic safety requirements for Class I, Division I, Group IIC environments. Consequently, users achieve reliable oxygen monitoring while maintaining workplace safety.

Core Sensor Technology

At the heart of every AST O2 analyzer and transmitter is an electrochemical micro fuel cell oxygen sensor. AST designs and manufactures these sensors in the USA specifically for oxygen measurement.

Because the sensors respond only to oxygen, they provide fast response, excellent stability, and reliable performance—even at sub-PPM concentrations. As a result, users benefit from accurate measurements and reduced maintenance requirements.

Built for Industrial Reliability

In addition to accuracy, AST analyzers deliver dependable performance in demanding environments. They respond quickly to process changes and integrate easily into control systems. Therefore, operators can identify oxygen excursions immediately and take corrective action without delay.

Commitment to Excellence

Ultimately, AST combines accuracy, reliability, and safety in every product. By delivering dependable oxygen monitoring solutions, AST helps customers protect personnel, maintain compliance, optimize processes, and improve product quality.
