AST-1012 Portable PPM O2 Analyzer

AST-1012 Portable PPM O₂ Analyzer

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

The analyzer allows field selection of any analysis range from 0–5 PPM up to 0–25% oxygen. In addition, the digital display provides a resolution of 0.01 PPM, which enables accurate monitoring of very low oxygen concentrations. At the same time, the analog output signal automatically locks to the selected measurement range, ensuring stable and consistent signal output.

Furthermore, the analyzer provides fast recovery from high oxygen levels. For example, the system recovers from air to 10 PPM in less than 45 minutes, which allows operators to resume trace oxygen monitoring quickly.

The AST-1012 Portable PPM O2 Analyzer operates with the AST-333 PPM oxygen sensor, which performs reliably in inert gases and gaseous hydrocarbon streams. Under normal operating conditions, this sensor offers an expected operating life of approximately 18 months.

For applications that require lower operating temperatures, the analyzer can operate down to -10 °C (14 °F) when used with the AST-333Z Oxygen Sensor. In addition to extending the temperature range, this Z-Series sensor shows excellent compatibility with gas streams containing any level of CO₂.

Moreover, the analyzer requires no routine sensor maintenance, other than periodic calibration. Finally, the instrument includes quick-connect sample inlet and outlet fittings, which allow fast setup and easy operation in the field.
