The Series 3000 Trace Oxygen Analyzers are rugged, microprocessor-controlled instruments designed for continuous or intermittent measurement of trace concentrations of oxygen. The Series 3000 Trace Oxygen Analyzers are available in single or three ranges, from 0-1 to 0-10,000 parts per million (ppm).

System Description
Featured with the instrument is an advanced electrochemical oxygen sensor that provides exceptional performance, accuracy, and stability. Its enhanced mechanical design ensures longer sensor life, and virtually eliminates leakage of electrolyte, a nagging problem with wet cells

The eloquence of the Series 3000 Trace Oxygen Analyzers are their ease of use. The Series 3000 Trace Oxygen Analyzers are equipped with three oxygen alarms and one status alarm relay, all of which can be configured for fail-safe operation. In addition to the alarm relays, each instrument is equipped with audible and visual alarm indicators. Available in a wide number of mechanical configurations from explosion proof (NEMA 7) to watertight (NEMA 4), the Series 3000 Trace Oxygen Analyzer affords maximum flexibility to meet the demands of the process control market. The Series 3000 Trace Oxygen Analyzer is priced thousands of dollars less than some other manufacturers. So before making that purchase decision, we would be delighted to submit a quotation for your consideration.
