AST-1019 PPM Oxygen Analyzer For Industrial Gas Analysis

AST-1019 PPM Oxygen Analyzer

AST-1019 PPM oxygen analyzer measures sub-PPM levels of oxygen in inert gases and hydrocarbon gas streams. As a result, many industries rely on this analyzer as an industry standard for trace oxygen measurement.

One of the key advantages of the AST-1019 analyzer is its field-selectable analysis range. Users can easily select ranges from 0–5 PPM up to 0–25% oxygen, depending on the application. In addition, the bright digital display provides a resolution of 0.001 PPM on the 0–5 PPM range. Consequently, operators can monitor extremely low oxygen levels with excellent precision.

Furthermore, the analyzer provides analog outputs of 4–20 mA and 0–1 VDC for system integration. The instrument automatically locks these outputs to the selected measurement range, which helps maintain consistent signal accuracy. At the same time, the analyzer maintains a minimum measurement range of 0–5 PPM, allowing accurate trace oxygen monitoring.

In addition, the AST-1019 analyzer includes two user-selectable oxygen alarm relays. Users can configure these alarms with latching or non-latching options, depending on process requirements. Moreover, operators can select a digital filter to improve the signal-to-noise ratio while still maintaining a fast response time.

The analyzer operates with the AST-333 PPM oxygen sensor, which measures oxygen in inert gases and gaseous hydrocarbon streams. Under ambient temperature and pressure, this sensor typically provides an operating life of 18–24 months, which helps reduce maintenance costs.

However, when gas streams contain low to high levels of CO₂, the AST-333Z Oxygen Sensor provides a better solution. This sensor handles CO₂-rich environments more effectively and still offers an operating life of 18–24 months. Therefore, it ensures reliable oxygen measurement in applications where carbon dioxide is present.

Extended Operating Temperature Range

AST-1019 PPM oxygen analyzer can operate in an extended temperature range down to -10 °C (-4 °F) when used with Z-Series oxygen sensors.

In addition, Z-Series sensors provide excellent compatibility with gas mixtures containing low to high levels of CO₂. This capability makes them suitable for demanding gas analysis applications where carbon dioxide is present.

Furthermore, these sensors offer a quick response time and long operating life of 18–24 months. They also require no routine maintenance, which helps reduce downtime and maintenance costs

AST-1019 PPM O2 analyzer is powered by a 100-240 VAC Universal AC/DC 5V Wall Plugin Power Adaptor. AST-1019 PPM oxygen analyzer can also be powered via a USB cable fitted with a recommended power jack.
