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).
