Series 3000 Trace Oxygen (O2) Analyzer / Sensor

O2 Analyzers

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).

Features Benefits

Safe to use

Some oxygen sensors must be initially filled with potassium hydroxide (caustic), a hazardous material. The Series 3000 Trace Oxygen Sensor is sealed; there is no such safety hazard.

Economically priced

Affords savings up to 50% and more over other electro- chemical oxygen analyzers.

Minimum maintenance

The Series 3000 Sensor never requires routine addition of water or potassium hydroxide. Operating costs are reduced.

Full sensor warranty Ensures cost-effective operation. Beware of "limited" or "pro-rated" sensor warranties. Warranty replacement of one of our competitor's sensor can exceed $3,000.

Visual and audible alarms

Ensures the highest level of protection.

Optional RS-232C or RS-485 communications Control several monitors on one communications channel along with security code protection.

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.
