AST-1012-P Portable % O2 Analyzer

AST-1012-P Portable % O₂ Analyzer

The AST-1012-P Portable % O2 Analyzer from Applied Sensing Technologies operates on a rechargeable battery, which allows convenient portable oxygen monitoring in the field. Because of its compact design, users can easily carry the analyzer for on-site gas analysis and system checks.

The AST-1012-P Portable % O2 Analyzer allows user selection of any analysis range from 0.1% to 0–25% oxygen. In addition, the signal output automatically locks to the selected measurement range, which ensures stable and accurate signal transmission. Furthermore, the instrument offers fast recovery from air to 0.1% oxygen in less than 45 seconds, allowing quick return to normal measurement conditions.

The AST-1012-P analyzer operates with the AST-222 or AST-222-4 percent oxygen sensor. These sensors perform reliably in inert gases and gaseous hydrocarbon gas streams and provide an expected operating life of up to 36 months under ambient temperature and pressure.

However, when gas streams contain carbon dioxide (CO₂), the AST-222-Z Oxygen Sensor or AST-222-Z-4 Oxygen Sensor is recommended. These Z-series sensors are compatible with gas streams containing any level of CO₂, which improves measurement reliability in CO₂-rich environments.

In addition, the analyzer can operate in an extended temperature range down to -10 °C (14 °F) when used with Z-series percent oxygen sensors. These sensors not only extend the operating temperature range but also maintain excellent compatibility with CO₂-containing gas mixtures.

Moreover, the analyzer requires no routine sensor maintenance, which helps reduce operating costs. Finally, the gas inlet and outlet are fitted with 1/8-inch compression tube fittings, allowing quick and secure connections for sampling applications.
