The Balston 72-730 and 72-O2730NA Oxygen Analyzers are designed to monitor the oxygen
concentration in a process stream, display this concentration in digital form, and provide
appropriate alarms and controls for protecting a process against undesirable oxygen con-
centrations. The oxygen analyzer is a valuable accessory for food packaging, solvent and
chemical blanketing, and purging applications.
Note: In hazardous applications where the oxygen content is critical (i.e., blanket-
ing explosive chemicals or packaging food for extended shelf life), an oxygen moni-
tor and/or trace oxygen analyzer should be used in conjunction with safety interlocks
and/or alarm systems to assure proper nitrogen purity levels at all times.
The Balston Oxygen Analyzer is a self-contained unit which may be wall-mounted, bench-
mounted, or ordered as an integral accessory to any Nitrogen Generation System. The unit is
powered by 120 VAC or 240 VAC, 50/60Hz. (Note: Main supply voltage must be within 10%
of nominal rated voltage for the generator.)
The Balston oxygen analyzer has been certified to IEC 1010 Standards (CSA 22.2 No.
1010.1-92) and bears the CSA safety marking on the product label.
The sensing device designed into the Balston 72-730 and 72-O2730NA Oxygen Analyzers
is a galvanic cell. The Oxygen Analyzer has an internal temperature compensation circuit to
provide accurate readings within a specified temperature range, with an accuracy of ±1% of
the calibration gas concentration.
The Balston 72-730 and 72-O2730NA Oxygen Analyzers have all the controls necessary to
assure safe and accurate monitoring of the oxygen concentration in a process stream. The
analyzers are equipped with the following controls and features (see Figure 1).

Page 2: Installation
Sample lines The Balston 72-730 and 72-O2730NA Oxygen Analyzers should be located indoors and as close to the process stream as possible to ensure accurate readings. Do not install the oxygen ana- lyzer outdoors. The location should be clean, dry, and between 59°F and 95°F (15°C - 35°C). -

Operation Calibration The 72-730 and 72-O2730NA are calibrated prior to shipment; however, Parker strongly recom- mends re-calibrating the units prior to initial start-up. After the initial start-up, the unit should be calibrated on a bi-weekly basis until a suitable schedule is determined, based upon the level of accuracy required by the application. -

(span gas) or 20.9% (compressed air). Close the valve from the calibration gas line and re-open the valve between the process stream and the analyzer. (Note: Parker recommends the use of a span gas with an oxygen content between 1% and 10%.) Alarm set points The high and low limits of the integral alarm may be set anywhere between 0.5% and 25%... -
