Portable Oxygen Analyzers

Portable Oxygen Analyzers – PPM and % Oxygen Measurement

Applied Sensing Technologies (AST) offers portable O₂ analyzers designed for accurate measurement at both PPM and percent levels. In applications where flexibility and mobility are essential, these portable units provide dependable oxygen monitoring without compromising precision. As a result, operators can perform spot checks, troubleshooting, and field verification with confidence.

Reliable Measurement Across Diverse Gas Streams

AST portable oxygen analyzers measure oxygen in inert gases, gaseous hydrocarbons, and gas streams containing reactive gases such as CO₂. Because many industrial environments demand precise oxygen control, these analyzers help maintain safe operating conditions and consistent product quality.

For example, operators use them for:

Continuous process verification and system checks

Glove box oxygen monitoring

Food packaging gas validation

CO₂ purification processes

Medical-grade oxygen measurement

Oxygen purity analysis

Confined space oxygen concentration testing

Whether in a production facility or a field environment, AST portable analyzers deliver fast and reliable readings wherever they are needed.

Designed for Safety in Hazardous Areas

In addition to performance, safety remains a top priority. Therefore, AST offers portable O₂ analyzers with optional intrinsically safe designs compliant with Class I, Division I, Group IIC hazardous area requirements. This allows safe operation in environments where flammable gases may be present, expanding usability without increasing risk.

Proven O2 Sensor Technology at the Core

At the heart of every AST portable analyzer is an industry-proven electrochemical micro fuel cell sensor engineered specifically for oxygen measurement. This sensor technology provides rapid response, excellent stability, and accurate detection from sub-PPM to percent levels.

Importantly, AST designs, develops, and manufactures these sensors in the USA. By controlling the entire development process, AST ensures consistent quality, long service life, and dependable performance even in demanding industrial conditions.

Precision Wherever You Need It

Ultimately, AST portable O₂ analyzers combine mobility, durability, and high-accuracy measurement in one compact solution. Whether verifying oxygen purity, monitoring trace oxygen levels, or ensuring confined space safety, these analyzers give users the confidence to make immediate, informed decisions in any environment
