AST-1019-OP Oxygen Purity Analyzer
Advanced Sensor Technology
AST-1019-OP oxygen purity analyzer measures oxygen up to 100%. For optimum accuracy, suppressed ranges of 90-100%, 95-100% and 98-100% are available. Display resolution, 2 digits after decimal point. Integral barometric pressure compensation enhances measurement accuracy. This is in contrast to the conventional oxygen analyzers where minor changes in barometric pressure can severely impact measurement accuracy.
User selectable two oxygen alarms, with latching or non-latching option. Fine tune temperature compensation. User selectable digital filter for optimal signal to noise ratio. Excellent overall system response time.
Integral oxygen sensor used in AST-1019-OP oxygen purity analyzer, AST-222-OP, has 24 months expected life in 100% oxygen. AST-1019-OP is a reliable, low maintenance alternate to much expensive Paramagnetic oxygen analyzers, for measuring elevated O2 . AST brand sensors are designed, developed and manufactured in the USA
- Proprietary electrolyte formulation and anode geometry offers extended sensor life even at 100% oxygen levels
- Fast response, 90% of step change in under 13 seconds
- Barometric pressure compensated
